Romeo Beckham - son of David and Victoria Beckham, natch - celebrated a big 6th birthday at Universal Studios on Thursday afternoon.
The party featured Romeo's siblings, Heidi Klum and her children with Seal, along with Gavin Rossdale and his son, Kingston Rossdale.
That's a lot of good genes - and celebrity babies that were spawned from them - in one place, people. Here's a photo of the outing ...
We hope you don't mind how many photos we've posted of Gwen Stefani and her family.
But when Kingston Rossdale in this adorable, how can anyone mind?!?
Another baby will be added to the brood any month now. You didn't think Stefani was just getting fat, did you?
The precious little spawn of Brangelina, Shiloh, is just the latest among many celebrity babies to celebrate a second birthday. But is the the cutest ever?

Kingston Rossdale turns two years old today. But the son of Gwen Stefani and Gavin Rossdale has already celebrated his birthday is style.
Yesterday, Kingston's parents threw him a party that includes ponies, cowboys, cowgirls and a number of celebrities.
Joel Madden showed up with daughter Harlow, though Nicole Richie was nowhere in sight. Victoria Beckham was also there with her youngest son Cruz, who arrived to the festivities in a monkey costume.
We wonder what the celebrity fashion police would say about that.

Just look out, Kingston. You're our favorite out of all the celebrity babies, but once the l'il sibling comes along, you're gonna get ignored!
Just kidding! Gwen and Gavin are way too awesome for that!
Kingston James McGregor Rossdale is closing in on two years old! Woo!
Call it Celebrity Look-Alikes: Cuteness edition. Or toddler edition. You can barely call Sean Preston Federline or Kingston Rossdale celebrity babies anymore - ding dang, them kids grow up so fast, right, Britney? But boy, we still love 'em.
Tell The Hollywood Gossip, readers: Which l'il fella do you think is cuter? The son of train wrecks Britney Spears and Kevin Federline (and brother of Jayden James), at left, or the son of rock stars Gwen Stefani and Gavin Rossdale?
Kingston Rossdale raises his arms in victory, virtually assured that he will win this popularity contest against Sean Preston Federline. But you be the judge.
While other celebrity babies garner all the attention, Kingston Rossdale just goes about his business of being cute.
There's Suri Cruise on the cover of Us Weekly, arms raised, basking in the glory of entertainment news photographers snapping her every move.
There's Jayden James, feeling sorry for himself and whining about his sucky mother to every paparazzi in sight.
And here's Kingston, just chilling with his mom, Gwen Stefani, playing chauffeur to a stuffed toy cat. He's a kid of the people.
