Julia Roberts -- Hot Bikini Mama of Three

"Mirror Mirror" star Julia Roberts proved she's still the fairest of them all by showing off her smokin' 44-year-old mother-of-three body this weekend in a hot black Tory Burch bikini.

With her classy lower back tat peeking over her bikini bottoms, the former "My Best Friend's Wedding" actress frolicked around the beach in Hawaii with her 3 kids -- Hazel, Phinnaeus and Henry -- and her RIPPED husband Danny Moder.
