ludacris-1 He's got hos in different area codes, but only one birthday, and rapper Ludacris is celebrating it in Sin City! Luda celebrated his 30th birthday last night with a celeb-studded party at Rio.

Producer Quincy Jones and actress Gabrielle Union passed birthday wishes, and "Everybody Hates Chris" actress Tichina Arnold serenaded the rapper/actor with a soulful rendition of "Happy Birthday."

Luda's nearest and dearest enjoyed a sit-down rappalicious dinner and watched some of the Atlanta rapper's favorite movies, including "Scarface" and, his own movie, "Crash." He's modest, too!
