Catherine Zeta-Jones and Michael Douglas appeared "really happy" at the Monte Cristo Awards this week.
The couple - who announced they were taking a temporary "break" from their 13-year marriage last August - seemed content in one another's company at the New York event and friends say their relationship seems well and truly back on track.
A source told People magazine: "They looked really happy to be together.
"Things seem to be going really well for them. I knew they were going to work as hard as they could on their marriage, especially for the kids. It's a good thing."
Catherine and Michael - who have son Dylan, 13, and daughter Carys, 11 together - are said to have impressed friends with their dedication to making their union work.
A source said recently: "It is so easy to just give up. But they wanted to put in the work. I'm really happy for them."
Michael's mother, Diana Douglas, first confirmed that he and Catherine were back together last month.
She said: "They are together. I knew they would work it out. They're both gentle people, not hysterical. They're always very affectionate and easy with each other. I figured the more everybody stayed out of it the better."
The couple had a difficult few years during which 'Red 2' star Catherine admitted that she suffers from bipolar disorder - which led to her spending time in rehab for depression - and Michael battled tongue cancer..

Margot Robbie was thrilled when she landed a huge catch during a fishing trip.
The 'Wolf Of Wall Street' star expressed her love of the outdoors during a recent holiday and shared a photograph of herself wearing a tiny bikini while holding a fish, a Giant Trevally, on Instagram, on Tuesday (22.04.14), which was Earth Day.
She accompanied the picture with the caption: "Fish are friends not food! #HappyEarthDay."
Her followers were quick to praise her big catch, posting "well done", with one adding: "Catch and release", urging her to drop the fish back into the sea.
Another saucy comment read: "Knows how to handle a big one."
The 23-year-old star was visiting Nicaragua and posted a number of other pictures to her social media account during her trip.
One includes her doing yoga with the message: "Sunset pool yoga (yeah it's going to catch on) #nicaragua (sic)", while another shows the brunette beauty enjoying some down time by the pool, along with the caption "wish you were here."
Meanwhile, the star will be back to work filming 'Tarzan' in coming weeks, in which she plays Jane alongside True Blood's Alexander Skarsgard as the lead role.
The new 3D production is set to be released in July 2016.

Joan Rivers has poked fun at Lindsay Lohan's miscarriage.
The outspoken comedienne even stunned her daughter Melissa with her remarks, which followed the troubled actress' revelation on her 'Lindsay' reality show at the weekend that she had recently lost a baby.
Asked what she thought about the news, Joan, 80, told TMZ: "I hope she kept it."
As Melissa recoiled in horror, she added: "Excuse me, what do you think I am? I was born with a coat hanger in my ear."
The 'Fashion Police' host then laughed when she was asked if she thought the 'Mean Girls' star would have made a good mother.
She replied: "She would have been diapering the wrong end."
Lindsay, 27, made the revelation on camera when explaining why she had taken a break from filming the OWN show, which chronicled her attempts to relaunch her career following her sixth stint in rehab.
She said: "No one knows this, and we can finish after this, I had a miscarriage for the two weeks that I took off."
After a long pause, the flame-haired beauty added: "It's a very long story," and failed to offer any other details, including who the father of her unborn child was.

Damon Albarn found heroin "very agreeable".
The Blur frontman, who began taking the drug in the 1990s after he came home to find then-girlfriend Justine Frischmann using the illegal substance, and admits it helped him think outside of the box when it came to writing songs, so doesn't "totally" think taking it was a mistake.
He said: "It was part of me growing up. Look, I didn't go out and look for it. I turned up at my house and there is was, made on the table. What should I have done? Leave my life and reject it, or stay in my own house and somehow assimilate it into my life? Once I tried it, I found it initially very agreeable, and very creative."
The 46-year-old singer - who has 14-year-old daughter Missy with girlfriend Suzi Winstanley - doesn't regret defending his use of heroin but admits his comments could be taken out of context.
Asked if it was a touchy subject, he told Time Out magazine: "I'm not touchy. I'm just aware there's an ambiguity and that my explanation can get lost in the sensational amplification of things.
"So I'm left with two options, either become really guarded and aloof, and return to this reputation I've had over the years of being a difficult b*****d, or I just don't talk at all. It's really frustrating."

Slipknot's Paul Gray was being prescribed Xanax in the weeks leading up to his death.
Doctor Daniel Baldi is on trial for the death of the group's bassist, who overdosed in May 2010, along with eight others, after allegedly giving him the drug despite his history of addiction.
A court heard on Tuesday (22.04.14), the musician spent his final weeks in a "blur" of extreme drug abuse which could have been prevented.
Paul's widow, Brenna Gray, questioned why Doctor Baldi was continuing to prescribe him the anti-anxiety drug when he was an addict in a downward spiral.
According to the Des Moines Register, she told the court: "I just knew it was his drug of choice, that he'd struggled with it.
"So I just wasn't really sure why he was on it, why he needed it along with the medication he was taking for addiction."
Brenna claimed she had showed his doctor photographs of Paul after he'd passed out in the hope he would take his drug abuse seriously and insists she tried to get his Slipknot band mates to stage an intervention but "none offered to help."
She made the claims during testimony at the trial at Polk County District Court in Iowa, after her husband was found dead at an Urbandale motel due to an overdose of prescription drugs morphine and fentanyl, which Baldi did not prescribe.
He denies nine counts of involuntary manslaughter and his lawyer claims he didn't prescribe the drugs that caused the deaths.

Robert Plant has ruled out a reunion show with Led Zeppelin.
The legendary frontman claims there is "zero" chance the band will come together for a live performance anytime soon, but guitarist Jimmy Page is confident fans would be keen for another show.
Jimmy told the BBC: "I'm sure people would love to hear it. I'm not the one to be asking, I don't sing."
The comments will come as a disappointment for fans who had hoped the group - also made up of Robert Plant, Jimmy Page and John Paul Jones - would do a repeat of their last big show at the 02 in December 2007, where they were joined by drummer Jason Bonham, son of the band's late John Bonham.
Meanwhile, the band are set to unveil a string of unheard tracks and early recordings when they reissue their first three albums on June 7.
Jimmy explained he felt "reassured" listening back to the group's early recordings, as he mused: "It's undeniable that we're good, the band was the real deal."
He also promised there will be "lots of surprises" on the reissues when the group's final three albums are re-released in 2015.

Ritchie Neville could smell that his girlfriend Natasha Hamilton was pregnant.
The 5ive singer and the Atomic Kitten star - who fell in love after appearing on ITV2 show 'The Big Reunion' last year - are expecting their first child together and before they knew Natasha was expecting, Ritchie sensed she was carrying a baby.
During a joint interview on ITV show 'Lorraine' this morning (23.04.14), he said: "I've got a little theory because I leant in [to kiss her] and I said, 'Have you used any baby lotion or something?' And she said, 'No why would I use that?' I said, 'Just in here [your neck] you smell like newborn babies.' She looked at me and I looked at her and said, 'You're not are you, you couldn't be [pregnant]?' It turned out she was."
Natasha has described her pregnancy as a "miracle" because she had numerous health issues which were affecting her ovaries in 2013 which could have resulted in her becoming infertile.
The 'Whole Again' hitmaker - who is already a mother to three sons, Alfie, Harry and Josh - revealed: "I had a lot of health issues last year with my ovaries and ended up in hospital. I was really poorly, I had a ruptured cyst and lots of pain and complications so the doctor spoke to me and said I may have to have my ovaries removed at some point which was quite a shock. In my head, I thought maybe that's why I had children young because in later life I was going to have health issues so it was just not on the radar, we weren't planning a baby and then when Rich was in Austria in January we had a little cuddle and..."
The baby will be Ritchie's first child and he insists his whole outlook on life has changed since he found out he is going to be a father.
He said: "It definitely is a life changer, even just on perspectives on the world and stuff, the world's a different place all of a sudden."

Amy Childs is planning on returning to 'The Only Way Is Essex'.
The 23-year-old beauty was catapulted to the spotlight following her time on the reality show and although she left the ITV2 series in 2011 she wants to make an appearance on the series in the near future.
In an interview with Star magazine, she said: "Never say never. I love the show and still watch it. When Lydia Bright turned up in the last series, my Twitter went mad with everything asking if I'll go back. I'll definitely do a cameo one day, maybe next year, I might shock everyone!"
Although there has been a lot of drama in Amy's life recently - with her being rumoured to have had a relationship with her married 'The Jump' co-star Darren Gough, a claim she has denied - she doesn't regret doing reality TV and claims she's excited about sharing her story with her children when she's settled down in the future.
Amy - who may also have to have her breast implants removed and put back in after her left implant detached from her natural tissue - explained: "With some things you have to laugh and I'm glad I can do that - some people might have a breakdown. When I have children I can't wait to tell them my story. I was a normal girl from Essex and then it all blew up for me!"

Former 'Coronation Street' actress Sarah Lancashire says there is "ludicrous prejudice" against soap stars in the acting industry.
The 49-year-old actress portrayed barmaid Raquel Watts in the ITV series from 1991 to 1996 and although she was always proud to be a part of the show, she believes she had to work harder to stop herself from being typecast.
In an interview in Radio Times magazine, she said: "Soaps are a double-edged sword. There can be prejudice from some writers and producers who feel you will lower the currency of their work if you've been in one. You have to rise above such ludicrous prejudice.
"Sometimes it's necessary for soaps to hang on to an audience by sensationalising ... but it's a great arena to learn your craft before you move on. There's no such thing as a 'soap' actor."
Despite going on to forge a very successful and diverse career following her time on 'Corrie', the 'Happy Valley' star would be happy to appear in a soap again in the future.
Lancashire - who returned to the cobbles of Weatherfield for one more episode in 2000 - added: "I won't say I'd never go back to a soap because an actor's life is so precarious. You can have the most wonderful patch when everyone wants to work with you, and in the blink of an eye the phone won't ring for a month, even a year."

Jerry Bruckheimer says bad timing has set back the studio's efforts to make 'Bad Boys 3'.
The 70-year-old star - who co-produced the 1995 original which starred Will Smith as Detective Mike Lowrey - insists a sequel to the 2003 follow-up is in the works but due other commitments the studio and actors haven't been able to make the movie.
He told collider.com: "It's so funny because we'll get Sony real excited to make the movie, and then Will [Smith] is off doing two movies. And then, Will will come back and be real excited about it, and Sony will say, 'Well, maybe it's not the time for this.' And then, 'Ride Along' came out and was a big hit, and now they're all excited to make the movie, but Will is off doing something else. It's just trying to get everybody together to make it. But, we're working on the script. We have a lot of faith and hope that we'll do it."
Meanwhile, Bruckheimer - who was honoured with a star on the Hollywood Walk of Fame last year - is working on 'Deliver Us from Evil' which will be released this summer.
