For a second there we forgot that Gavin Rossdale doesn't just have three boys -- he has a daughter too!

On Wednesday afternoon Gavin and his 25-year-old daughter Daisy Lowe lunched in Beverly Hills, and the two seemingly had a blast catching up. Daisy flew in from London a few days ago, and after grabbing a bite with her pops, she headed to the Chateau Marmont.

Daisy found out over a decade ago that the Bush frontman was her father, but apparently he wasn't too keen on taking a paternity test when Daisy's mother, Pearl Lowe, initially requested one. Glad that all worked out!
