Jennifer Lopez and her husband Ben Affleck were joined by his ex-wife Jennifer Garner on Sunday to celebrate a musical event featuring family.

The 53-year-old Shotgun wedding star and the 50-year-old 13 Going On 30 star were seen joined by their children as they arrived at a performance hall in Santa Monica, California.

The meet-up showed how seemingly cozy the blended family and exes have become since Affleck married Lopez last year.

Lopez and Affleck were both seen looking affectionate with her child Emme, 14, while Garner was spotted arriving at the venue with her older daughter Violet, 17, and son Samuel, 10, while Seraphina, 14, was presumably already in the venue.

Jennifer also wore an olive-colored set of platform Louboutins, which elevated her 5ft5in stature.

Jennifer’s sighting comes on the same day that new images were released from the upcoming third-season revival of the cult comedy series Party Down.

The series was canceled after its second season in 2010 due to low ratings and the loss of cast members Jane Lynch (who skipped the second season to appear on Glee) and Adam Scott, who would have left to appear on Parks And Recreation.

The revived third season features several original cast members, while Garner will be joining as a movie producer who is now Scott’s girlfriend.

Lizzie Caplan previously played his co-worker and love interest but was unable to join the third season due to scheduling issues.

Jennifer Lopez’s meeting with her husband’s ex-wife comes after she opened up about the joys of joining a blended family while speaking with Extra at the premiere of her new romantic comedy Shotgun Wedding on Wednesday.

‘It’s going really, really well, it’s amazing, we have five beautiful, beautiful children, blessings…’ she said of the children.

‘We dropped one of them off at school today and we were just kind of thinking about what our lives have become and just feeling so blessed and grateful for where we wound up in our lives,’ she continued. ‘It’s a beautiful night, that’s all I can say.’

During an appearance on Today earlier this week, Jennifer said she had had her ‘best year’ in a long time after she and Ben moved in together and their children could finally be together under one roof.

‘We moved in together, the kids moved in together. So it’s been, like, a really kind of emotional transition. But at the same time, like, all your dreams coming true and it’s just been a phenomenal year. Like, my best year, I think, since my kids were born,’ gushed.

While speaking with People, Jennifer delved into how she tries to juggle her busy singing and acting careers with her obligations as a mother and now a stepmother.

‘I put my best foot forward as much as I can,’ she said modestly, before adding that she prefers to keep it to herself when she’s stressed out by her obligations.

‘I’m not one to share my angst. I don’t feel like that’s my life as a performer. You always show the best of you,’ she explained. ‘But I’m a human being like everybody else, and I suffer in silence at times.’

The pop star added that she had to think carefully about how many personal details she was willing to reveal to the public in her music.

‘I’ve been thinking a lot about that — like, what parts of myself do I share with my audience? And what it means to be an artist and to be authentic,’ she continued. ‘And I feel like there are some things that need to be said and shared because I think, like you just said, it’s like, “Oh, you have it all together.”‘

Jennifer added, ‘But the truth is, I’m just like anybody else. I struggle at times, and I wonder at times and I doubt at times, and I’m insecure.’

The hitmaker is set to release her ninth studio album, This Is Me … Now, later this year, though a release date hasn’t yet been announced.

The LP is the spiritual successor to This Is Me … Then, which she released in 2002 during her first relationship with Ben.
