Chris Martin has introduced Jennifer Lawrence to his friends.
The 37-year-old Coldplay frontman reportedly invited 'The Hunger Games' actress' to a dinner at Chateau Marmont in West Hollywood with his pals.
A source told E! News: "They seem very comfortable in each other's company - and happy!
"It doesn't seem like it's a new relationship. They seem super affectionate and at ease with each other."
Chris has reportedly been dating the 24-year-old actress since June and the couple was the "centre of attention" at the restaurant.
The source added: "She is very gregarious and confident ... They seem super cute together."
Jennifer - who was seen holding hands with Chris throughout the night - is the first person the singer has romanced since ''consciously uncoupling'' from Gwyneth Paltrow earlier this year after 10 years of marriage.
Meanwhile, it has been revealed that the 'A Sky Full Of Stars' hitmaker has been trying his best to win over Jennifer by writing love songs for her.
The insider said: "He writes her songs and loves taking her to private romantic spots. Chris is sweeping Jen off her feet. That's his thing."

Jennifer Garner thinks her husband, Ben Affleck, could bench press her.
The 42-year-old actress has revealed her husband is looking "buff" after his countless trips to the gym to shape up for his role as Batman in upcoming blockbuster, 'Batman v Superman: Dawn of Justice'.
She told Extra TV: "Big Ben is definitely looking buff... I think he's eight or seven percent body fat and all muscle.
"I can't keep up with him, clearly. He could bench me, but yeah, we work out at the same time. I do my little mini workout."
Meanwhile, the 'Men, Women & Children' star gushed about Ben's "insane" physique but revealed she didn't mind whatever shape he was.
She explained: ''He was in crazy shape for 'The Town'. I've seen him kind of in every different variation, so I'll take him however I can get him!
"But as long as this is the guy I'm married to, I'm kind of like, 'Wow! That's crazy!' He looks insane. He's worked really hard.''
The couple - who have three children, Violet, eight, Seraphina, five, and Samuel, two - have admitted their hectic schedules mean they have to make more of an effort to spend time as a family.
Jennifer said: "When we had our first, we had only been together a year. We were babies. It happened so fast, I hardly even remember what we were like before the kids got here.
"Now we're just starting to go away for a night here and there ... But we're definitely in a very mindful place where we're making an effort to be together, do things at the same time, and be loving."

The reality star then posted an inspirational quote on Twitter, which appeared to be related to her romance.
She tweeted: ''Be grateful for what you have and stop complaining - it bores everybody else, does you no good, and doesn't solve any problems.'' Amen (sic)''

Christina Aguilera is reportedly upset that Gwen Stefani has replaced her on 'The Voice' USA.
The 'Your Body' hitmaker is taking a break from the series after giving birth to her daughter - Summer, who she has with fiancé Matthew Rutler - last month, but she is said to be concerned she won't be asked to return to the show next year.
A source said: "Christina is extremely threatened by [her temporary replacement] Gwen. She knows that if the ratings are higher on Gwen's season than they were on hers, the producers may have no choice but to ask Gwen to stay on."
The insider added: "Christina's in a world of paranoid right now."
The blonde beauty, 33, who also has son Max, five, with her ex-husband, Jordan Bratman, is also said to be concerned about Taylor Swift's role on the show with 24-year-old singer set to join the series as an advisor.
But the source told OK! magazine: "She's ready to fight for her spot."
Up until this year, Christina has shared a rotating spot on the judging panel with Shakira, who is also expecting her second child.

Jamie Dornan insists that 'Fifty Shades of Grey' won't be "grotesque".
The handsome actor insists the latest film - which is based on the erotic trilogy by author, E.L. James - will not be too dirty for audiences to enjoy, but admits it will "break a few boundaries".
He explained: "You've got to make something a large amount of people can go and see. It's not going to be grotesque.
"I mean, in some ways, it'll break a few boundaries. But at the same time, they want to put bums on seats. They can't alienate an audience. You know it has to be watchable. It can't be hardcore. I wouldn't have signed up for it if it was."
The 32-year-old star also admitted he wasn't worried about filming the explicit scenes with his co-star Dakota Johnson.
Jamie added to GQ magazine: "I'm not really fearful of that stuff. It's just work. It's strange work, sure, but it's still work. I just get on with it."
He even revealed that his father had encouraged him to take on the role of Christian Grey, as he added: "[Dad] was all for it. I don't come from a cagey family. We're fairly liberal."

Jessie J 'Photoshopped' her cellulite.
The 'Bang Bang' hitmaker has admitted she erased traces of the unsightly wrinkles from her legs in the cover photo for her latest album 'Sweet Talker'.
Jessie, 26, who appears in nothing but a pair of black high-waisted briefs, a black bra and heels in the artwork for her latest offering, was determined to keep the image as natural as possible but was forced to touch-up areas of stubborn cellulite following the shoot.
She told OK! magazine: "I'm in my underwear. What I like about it is none of it is touched up - apart from the cellulite here. I was like, 'Please get rid of my cellulite.' "
As well as the striking cover, the brunette beauty admitted she is extremely proud of her third studio album as it reflects her personality more than her second offering 'Alive' which was "too quiet".
She added to OK! magazine: "I'm proud of it. I sing my a**e off, I don't hold back. I'm an over-the-top singer - there are not many of us around anymore.
"Even when I was nine-years-old auditioning for Anne - 'The sun'll come out, tomorrow!' - I wasn't quiet. I can't be that girl and on the second I tried to be that a little too much. "

Jay Z has been "going all out to treat" his wife Beyonce during their weekend in Paris.
The rapper is said to be spending a few days in the French capital with his lover - as part of their jointed tour 'On The Run' - and he is keen to dispel any rumours the superstar couple are "heading for a break".
A source told the Daily Mirror newspaper: "It's been a really rocky summer for Jay and Bey and they want to put to bed all the rumours that they're heading for a break.
"That's why Jay is going all out to treat Bey in Paris. They have some great memories of the city from their early days together and he wants to remind her of that.
"He's planning a super-fancy late dinner after the final show and is thinking about L'Avenue, one of their favourite places they always love to visit in Paris."
The couple performed the first of two shows at the Stade De France last night (12.09.14), and it is said with the tour coming to an end they are keen to focus on their life "as husband and wife".

Kim Kardashian West and Kanye West are taking private yoga classes naked.
The superstar couple are said to have started the raunchy sessions as a way to keep the rapper calm, while also "spicing up their love life".
An insider told the Daily Star newspaper: "It was after their second yoga session with a private instructor at their home that Kim suggested to Kanye that they strip off to do their homework.
"They did their yoga poses for about 30 minutes, both completely naked.
"Not only is it making Kanye calmer and more relaxed, but the yoga is also spicing up their love life."
It is said the 'Bound 2' rapper was open to the idea of yoga, particularly because he sees himself as "spiritual and a great thinker".
The source said: "Kim knows Kanye has an ongoing battle with keeping calm, so she suggested they do yoga together and maybe meditate to help clear their minds.
"He was all in favour of the idea because he likes to think of himself as being spiritual and a great thinker."

Kelly Brook has wasted time on "stupid boys".
The glamour model - who is engaged to David McIntosh - has hit out at her former lovers, including Danny Cipriani, and insisted the realisation about the men from her past was what prompted her to write her memoir 'Close Up'.
She told the Daily Mail Weekend magazine: "Oh, I've wasted so much time with stupid boy and doing stupid things, there's been so much written about me, I thought it's about time I closed the door on all those chapters.
"I've been so defined by those relationships and things that have happened, I wanted to put my point of view across. That way I can move on.
"I wanted people to understand what happened, and I'm not a victim. It's just the nature of things. If you dance with the Devil, you get burnt."
Kelly claimed Danny was a needy man who craved "constant attention", and insisted she then realised "all these men" were "spineless".
She added: "He needs constant attention from any woman at any time and if you're not going to give it to him there's a whole life of women who are ready to.
"From the attention of his own mother to his friend's mother to glamour models. It's endless. I started to think all these men are absolutely spineless."

Gary Busey has won 'Celebrity Big Brother'.
The 70-year-old actor - who was the favourite to win the show - beat boxing star Audley Harrison, despite causing controversy amongst his fellow housemates.
Addressing the crowd as he exited the house, Gary said: "I can't tell you this feeling of enlightenment and loving love from Britain and all the housemates that I lived with and everyone here.
"I know why the word 'Great' is front of Britain."
In his interview with Emma Willis, he added: "It's a feeling of surprise and honour and a tribute to my love for this country."
Meanwhile, Gary - who is the first American winner of the show - admitted he had no idea what the house would be like.
He said: "I saw the housemates and it was like: 'Wow this is great'. I had no idea what I would be up against and people challenging me.
"When you've been around the sun 70 times ... you've got a new knowledge of life and you've got a new knowledge of humour and you learn to respect the youth ... That's life, that's evolution, that's growing up. I didn't know what to expect."
Gary - who has starred in Hollywood hits such as 'Lethal Weapon' and 'Point Break' - revealed the show had changed him as a person.
He explained: "When I go back home, I'm a changed man. I will be with my sweetheart wife Steffanie everywhere she goes. I will read my son Luke books every night to go to sleep ... it's great."

An explicit video by Louis Smith has reportedly been sold to a celebrity sex-tape company.
The 'Tumble' judge is said to have appeared in the racy clip - made on Skype - three years ago and it is "terrible timing" for the star, who is keen to forge a TV career for himself.
A source told The Sun newspaper: "It's terrible timing for Louis. He's desperate for a TV career but 'Tumble' is aimed at a family audience."
The 25-year-old gymnast - who won a silver medal at the London 2012 Olympic Games - reportedly appears in the video to do a routine before stripping, talking about sex and performing a solo act.
It is said the raunchy clip was made with a model, who has now sold it to the Celebrity Busted web firm, with sources claiming it could "damage" his reputation.
An insider added: "It's unfair this could damage him all these years on."
Louis recently admitted he hoped 'Tumble' would show gymnasts and other athletes in a more positive light, insisting they "can have a laugh".
He said: "It's frustrating when you've got a different side to you and people always see you doing the same interviews and being asked the same questions, 'How do you feel about the Olympics?' How's training going?'
"You feel like you've been moulded into this respectable kind of person. This is an opportunity to show the other side of sportsmen. We can have a laugh and enjoy ourselves too."

Sheridan Smith says playing Cilla Black is the closest she'll get "to being a pop star".
The actress is starring as the iconic singer and TV star in ITV's new series 'Cilla', and getting to sing her songs at the legendary Cavern Club in Liverpool - as well as record them at the Abbey Road studio in London - was an amazing experience.
She told the Daily Mirror newspaper's We Love TV magazine: "Oh my God, that was such a privilege.
"Performing the rock 'n' roll numbers at the Cavern was also brilliant fun.
"All these extras were screaming at me while I was on stage. It's the closest I'll get to being a pop star."
Meanwhile Sheridan, 33, admitted it was also a chance to experience the 1960s - an era she was born too late to enjoy.
She explained: "This show is about Cilla and capturing the buzz of the Merseybeat era.
"There's never going to be a time like that again. I wish I was around in that era, but playing Cilla is the next best thing."
