Kelsey Grammer nobu dinner children beard

Kelsey Grammer, 55, sported a new, gray beard as he and his kids (and wife Kayte Walsh, 29) headed to dinner at Nobu in Malibu on Wednesday.

Kelsey's gorgeous ex, Camille, and her hunky, Greek god boyfriend Dimitri, a lawyer, were out in the 'Bu the night before.

Jersey Shore's Snooki Tweeted on Wednesday, "Everytime I see Kelsey Grammer I think of what a dumba** he is for leaving his hot a** house wife. -_- bye."

Snooki, we second that! Camille is proving herself to be such a strong woman on the current season of Real Housewives of Beverly Hills -- she's movin' on, and Dimitri is a total UPGRADE!
