Kate Hudson stopped off for lunch with friends at Sugarfish in Brentwood, CA, on Friday. Kate was without her boys Bing Bellamy and Ryder Robinson on the outing, though the trio did travel together earlier in the week. The first clip of Kate Hudson on Glee came out this week, showing that the hot mom has some equally sexy dance moves up her sleeve. Glee isn't the only important musical release in her future — Kate's fiancé Matthew Bellamy's band Muse has an album coming out in October. Kate and Matt may not have duets in their future, but baby Bing apparently will make an appearance on the record. Matthew told Rolling Stone that an iPhone recording of the sound of Bing's heartbeat right before he was born is featured on the track "Follow Me."
