When Brits collide!

The whole Osbourne clan was out for dinner celebrating Jack's birthday last night when they ran into England's second most famous family - the Beckhams!

Kelly O, who is close friends with the former Spice Girl, took the opportunity to chat with her pals and snap pics with them, which she uploaded to her Twitter account.

"Nothing beats running into one of my favorite fashion designers and friend @victoriabeckham #GirlPower," she captioned the snapshot.

The joyous unplanned run-in was the cherry on top of the family fete, which also included Jack's wife Lisa Stelly. It looks like baby Pearl was left at home with a sitter while her parents wined and dined.

Earlier in the day, the couple made the most of the rainy weather and visited a local L.A museum to take in the sights.

Happy birthday Jack O!
