Robert Downey Jr. was invited to share a Jacuzzi with Chris Evans when they first met.
The 'Iron Man' actor claims his 'Avengers' co-star asked him and wife Susan Levin back to his home to share a hot tub with the "hot girl" he was dating.
Downey told Variety: "I have a vague memory of seeing him and whatever hot girl he was dating across from a dinner with me and Susan. I think he and his girlfriend invited Susan and I back to their house to get in the Jacuzzi, to tell you the truth."
The 48-year-old actor admits he isn't too sure on the exact details of the evening, but he insists Chris' invitation was politely declined.
He joked: "[Did we join them?] No, we did not, and by the way, like I said, that's a vague memory, but that's what I'd like for you to print."
The pair remain good friends and Downey - who has 20-year-old son Indio from his first marriage to Deborah Falconer and two-year-old Exton with Susan - claims to be such a big fan of Chris' lead role in the 'Captain America' franchise, he is going to host a special screening for the upcoming sequel 'Captain America: The Winter Soldier' as part of his birthday celebrations.
He said: "I'm not kidding. I'm having 50 kids over and I'm screening 'Captain America 2' on my birthday, which happens to be the day it opens. I haven't seen it. That's one of the perks of being on the inside track at Marvel. I hope it's not watermarked too heavily."

Gary Barlow admits he still gets "nervous" before releasing new music.
The 'Let Me Go' singer claims he still worries about what his fans will think before he brings out new material, despite having conquered the charts as both a solo artist and with his band Take That.
He told 'This Morning': "I'm always nervous around the release of anything because it's your latest work, you've tried hard, you've taken a year to make it or something and you're just giving it and saying 'do you like this or not?'..."
The 43-year-old star has also announced his next single will be 'Face to Face', a collaboration with Elton John, which was recorded at the famous Abbey Road studios in London earlier this year.
He said: "It was my idea ... I was ringing him up pestering him! But for me, because he's my idol, he's the reason I first sat on a piano stool and it was just such a treat to be with him and record a duet. It was fantastic."
Speaking about touring without his Take That band mates - Robbie Williams, Jason Orange, Mark Owen and Howard Donald - he insists he still enjoys the shows.
He said: "I actually really enjoy touring by myself, you know, it's all on your shoulders and I quite like the pressure. But I'm really looking forward to playing all these new songs. And some of the old stuff as well."
Gary added: "I've videoed Elton singing the song [Face To Face], so he's going to be on the big screens, although I said to the production man 'don't make him bigger than me, it's my show remember!'"
When asked if he'd ever pose naked, Gary also laughed and said: "No! Definitely not. I'm trying to keep hold of my fans, not lose them."

Jason Derulo thinks being on tour is like a "vacation".
The 'Talk Dirty' singer insists he has fun on tour despite his hectic schedule and isn't "miserable" like a lot of artists who perform many dates in different countries because he drinks alcohol and doesn't promote the gigs much.
He told BBC Radio 1: "I'm on this world tour, it's like a vacation. I don't do any promo. It's always just about the tour, it's a lot of fun. I get lots of sleep, I work out and do a show. It's like heaven."
The 24-year-old star is currently on his 'Tattoos World Tour' and told presenter Nick Grimshaw he's looking forward to heading to Australia in coming months.
He said: "We've been on the European run for about two months now. We got about two more months left doing Australia and New Zealand and all that.
"It's amazing, it's [my popularity] spread out pretty well, I've been truly blessed. [But] Australia is a little different, I think I've had about 25 Top 5 records there. I don't know what it is about Australia."
Meanwhile, Jason has cut out meat in order to shape up even more for the rest of his live dates, after being encouraged by his backup dancers.
He said: "For the past two weeks I've stopped eating meat all-together. I got a couple of dancers that don't eat any meat and I was on stage one day and I was like, 'Wait a minute, these guys are trying to upstage me', their bodies were starting to look different, so I like, 'Let me try this'.
"It's been kind of hard because everyone around me eats great stuff ... chicken [and] burgers, but I'm starting to like fish a lot more now."

Jamie Chung is embarrassed to watch her fiancé in 'One Tree Hill'.
The 30-year-old beauty - who stars in Alfonso Cuaron's new TV drama 'Believe' - has revealed she got a "kick" out of Bryan Greenberg's role as angsty heartthrob Jake Jagielski in the hit teen drama but found it awkward to watch him.
She told BANG Showbiz: "I never really got into that show [when it was on air]. But we were together at a hotel and one of the episodes came on. I just couldn't ... it was so dated - the moppy hair, the chokers, the puka shell necklaces. I was like, 'I can't watch this, Brian, I'm so sorry.' I got a kick out of it."
The former reality TV star has built up an impressive acting career since finding fame on 'The Real World', and she admits she often turns to Bryan, 35, for career advice.
She explained: "It's always so much easier to think outside the box when it's not the project you're working on, and we certainly help each other. It's quite awesome to be in a relationship that understands the business. He's a lot more seasoned than I am and I feel like I get a lot more help from him. I couldn't have asked for anything better."
Jamie plays Channing in new US sci-fi drama 'Believe' and she feels incredibly lucky to work with the show's executive producer Alfonso Cuaron, who recently won an Academy Award for Best Director for 'Gravity'.
She gushed: "It was like a sweep ... six other Oscars! Before, I was like, 'Alfonso's a great director.'
"He's so down to earth and nothing really gets to his head. I was like, 'Holy crap, he's an Academy Award winner!'
"He's the best of the best and we had the opportunity to work with him.
"He's such a good person, and a hard worker, he really deserved it."
'Believe' begins on Thursday 27 March at 9pm on Watch (Sky 109/Virgin 124).

EastEnders' Lola Pearce is to be run over by Ronnie Mitchell.
The teen mum - played by Danielle Harold - will be left fighting for her life after she is accidentally ploughed down by the blonde businesswoman (Samantha Womack).
Lola's family rush to her bedside after the fatal accident, which leaves Ronnie absolutely devastated.
The crash is set to bring back heartbreaking memories for Ronnie, who lost her daughter Dannielle Jones (Lauren Crace) back in 2009 when she was mowed down by Walford's serial killer Janine Butcher (Charlie Brooks).
Meanwhile, show bosses previously promised that Ronnie, who fled Albert Square for two years after abducting Kat and Alfie Moon's (Jessie Wallace and Shane Richie) newborn son Tommy, would have a "darker" side to her.
Viewers recently saw Ronnie murder the nefarious Carl White (Daniel Coonan) - who had been wooing her sister Roxy Mitchell (Rita Simons) - and Samantha, 41, admitted the dramatic scenes have been an interesting challenge.
She said earlier this month: "It's strange coming back with such a big storyline and being a different character, but at the same time, it's like coming back to family ... they're all my family, they genuinely are. Even when you're dealing with a difficult storyline and it feels really weird and out of the normal, that's cool creatively. I'm embracing it."

Lauren Goodger was left looking "like a chipmunk" after undergoing laser treatment.
The former 'The Only Way is Essex' star sparked rumours she has had plastic surgery after she was spotted with a fuller face earlier this week, but the brunette beauty claims her change in appearance is down to a skin peel procedure she underwent while she was in the US last week.
Writing in her new! magazine column, she said: "While I was in LA, I had a mild CO2 laser procedure done to my face, but that's it. It burns off the top layer of your skin so you develop new skin cells to make your face smoother, firmer and younger looking.
"I had it done around my eyes and mouth to bring out the natural collagen and the doctor warned me my face would stay puffy for up to two weeks afterwards.
"I looked like a chipmunk when I left the clinic, but it's calmed down since."
The 28-year-old beauty - who has had a nose job and breast enhancing surgery - claims she's never had Botox and insists her youthful looks are down to "good makeup"
She explained: '"I can assure you I haven't had anything done - it's just clever make-up."

Chris Evans is planning to give up acting.
The 32-year-old actor - who is currently stars as the titular superhero in 'Captain America: The Winter Soldier' - has admitted that aside from his Marvel commitments which he is contractually bound to, he won't be taking on any more acting jobs.
He said: "I've known for a while I wanted to direct. But [time] never really opens up. There's another movie to do, there's another acting job. It just got to a point where I was like, you know what - I have to do this.
"If I'm acting at all, it's going to be under Marvel contract, or I'm going to be directing. I can't see myself pursuing acting strictly outside of what I'm contractually obligated to do."
Despite claiming that he's no longer interested in acting, the 'Fantastic Four' star - who recently made his debut as a director on '1.30 Train' - has confessed that his roles in movies such as 'Captain America' have allowed him to pursue a career in directing.
He told Variety.com: "Without these movies, I wouldn't be directing. They gave me enough overseas recognition to greenlight a movie. And if I'm speaking extremely candidly, it's going to continue to do that for as long as the Marvel contract runs."
Evans, who admits he struggles with fame because he likes to do "normal things", confessed he could change his mind about ending his acting big-screen career in the future.
He added: "For all I know, in five years, I might say, 'Shit, I miss acting.' Right now, I just want to get behind the camera and make movies."

Ricky Gervais loved the "realism" while acting with the Muppets.
The 52-year-old star hits the big screen in the 'Muppets Most Wanted' alongside children's favourites Kermit the Frog, Miss Piggy, and the rest of the famous clan.
Gervais enjoyed working with them because unlike other films which require computer-generated imagery, like the 'Night In The Museum', the characters in this movie are visible while filming.
Talking at film's press conference at London's Soho Hotel today (25.03.14), Kermit said: "It's tough to choose someone fictional [to work with] because we're the only ones who aren't computer generated, you see, they're not really there."
Constantine - who plays the villain - added: "You couldn't see them at a press conference."
Gervais explained: "I've done 'Night In The Museum', just done three, Ben Stiller is in it a lot and he's in the scenes when all the animals come alive, but they're not really there. So, he spends six weeks running around talking to a tennis ball on a stick whereas with this, you're acting, you're acting with these guys! It's brilliant fun, but it also makes a difference with the timing and the realism and the affection for it. I mean it's real."
'Muppets Most Wanted', which is directed by James Bobin, follows the Muppets on tour in Europe where they unwillingly find themselves mixed in criminal behaviour.

James Rebhorn wrote his own obituary before he died.
The 'Homeland' actor passed away on Friday (21.03.14) aged 65 following a lengthy battle with skin cancer, and wrote a touching piece in which he paid tribute to his late parents, wife Becky and their daughters Hannah and Emma at some point during his final days.
The full piece was first posted on the website for his church, St. Paul Lutheran Church in Jersey City, New Jersey and praised his parents for giving him "faith and wisely [encouraging] him to stay in touch with God."
The obituary went on to describe James' wife and their children as the "centre of his being".
He wrote: "They anchored his life and gave him the freedom to live it. Without them, always at the centre of his being, his life would have been little more than a vapour.
"His children made him immensely proud. Their dedication to improving our species and making the world a better place gave him hope for the future. They deal with grief differently, and they should each manage it as they see fit. He hopes, however, that they will grieve his passing only as long as necessary."
And the 'Scent of a Woman' star concluded the writing to thank those who had helped with his career.
He closed: "Jim was fortunate enough to earn his living doing what he loved. He was a professional actor. His unions were always there for him, and he will remain forever grateful for the benefits he gained as a result of the union struggle. Without his exceptional teachers and the representation of the best agents in the business, he wouldn't have had much of a career. He was a lucky man in every way."

Rumer Willis wants to open a nightclub.
The 'House Bunny' star inherited "many millions of dollars" from her famous parents Bruce Willis and Demi Moore when she turned 25 last year, and is now looking for an investment opportunity in Hollywood.
A source told RadarOnline.com: "Rumer came into many millions of dollars last August on her 25th birthday and got full control of the trust Bruce and Demi set up for her.
"She wants to use it to invest in a hot business and has been telling friends she wants to own a nightclub. She's begun scouting existing Hollywood spots that could use her 'touch'."
However, the insider doesn't think Rumer will get the backing from her parents - who divorced in 2000 and have two other daughters, Scout, 22, and Tallulah, 20, together - for her new venture as their own foray into the hospitality industry was unsuccessful.
The source added: "Bruce and Demi had a bad experience in the club and restaurant business when they backed the once-famous Planet Hollywood chain that eventually flopped, so it's doubtful that they'll like the direction Rumer wants to take her investments.
"But Rumer has largely lost the acting bug and now that she's financially independent, she's going to try a lot of different things that don't involve her parents' careers."

Chris Hemsworth and Elsa Pataky have named their twins Tristan and Sasha.
The couple - who already have daughter India Rose, 22 months - welcomed the boys into the world earlier this month and now the Spanish actress has revealed what they have called their two sons.
Posting a picture of the twins' feet on her Instagram page, she wrote in Spanish: "You are home! Tristan and Sasha came to this world on March 18 just after the full moon. Complete happiness."
Elsa has also advised new parents to treasure every minute with their babies.
Writing in a blog post for Spain's Glamour magazine, she said: "Enjoy every second with your baby because it is the most wonderful thing of the world."
Proud father Chris, 30, previously gushed about family life and admitted he is happiest when he is with his wife and daughter.
He said: "Being a father is certainly a task. But the best one that I could ever ask for. Being home, being with the family, that's what it's about ... It makes me much more relaxed with work, because I have something that is far more important to me now."
The actor married Elsa, 37, in 2010 after a whirlwind romance.

Lauren Conrad has had to tone down her "girlie" home since her fiancé moved in.
The former 'Hills' star is a fan of overly feminine and vintage styles of decor, but admits her partner William Tell doesn't share her tastes.
She said: "If it was up to me, my home would just be over-the-top girlie and vintage but I share my home with a gentleman now."
And the 28-year-old beauty is trying to curb her habit of working from her bed.
Speaking to the new issue of Allure magazine, she said: "Your bed is for sleep and sex."
The fashion designer also revealed the key to her laid-back style.
She explained: "Take any trend you want and relax it. That's how California does it. If it's silk button-up shirts that are in, you probably don't button them all the way, and you cuff a sleeve, you know what I mean?
"It's almost like how your outfit looks at the end of the day."
Lauren is a big fan of hair extensions and wouldn't be without them to boost her locks.
She said: "I can't remember the last time I didn't have extensions.
"Extensions are great. And they've come so far in the last few years."
