Mila Kunis and Ashton Kutcher were just a couple of the famous faces living it up in L.A. on Friday night at Jenna Dewan-Tatum’s 35th birthday bash. It’s a rare event for Mila Kunis to go out and leave baby girl Wyatt at home.

Dancing the night away at Bootsy Bellows in Los Angeles, the gang also included Selena Gomez, Niall Horan, Adam Levine, Behati Prinsloo, and Louis Tomlinson.

Jenna Dewan-Tatum’s actual birthday was Thursday, but it seems hubby Channing Tatum knew Friday was a better night for friends like Mila Kunis and Selena Gomez. He planned the bash, and spent the evening canoodling with his pretty wife.

A source says Mila Kunis, Ashton Kutcher, Dewan-Tatum, and her hubby all enjoyed one another in addition to enjoying themselves.

“They were all laughing hysterically together and having the best time,” a source tells People magazine.

At least Mila Kunis and Ashton Kutcher were well-behaved. Selena Gomez and Niall Horan made news for excessive PDA–lots of hugging, kissing, and dancing close. Justin Bieber must be bummed.

It would have been fun to be that proverbial fly on the wall at Jenna Dewan-Tatum’s birthday bash, if for no other reason than to see her and her hubby interact with friends like Adam Levine, Behati Prinsloo, Mila Kunis, and Ashton Kutcher.

So far the photos that have emerged from the event assure everyone that lots of fun was had by all.
