Joey, Matthew and Andrew -- who all co-starred on the sitcom "Brotherly Love" together from 1995-1997 -- reunited this weekend in Las Vegas, where they celebrated Joey's 36th birthday.
Matthew, 32, and Andrew, 24, joined Joey for a weekend of fun in Sin City, where they feasted at Sugar Factory American Brasserie on Saturday night. We're told the group was given a platter of delicious sweets -- including white and milk chocolate covered Twinkies -- as they sang "Happy Birthday" to Joey.
From there, they went to the Chateau Nightclub and Gardens at Paris Las Vegas where they had a table at one of the club's VIP section.
We hear the women at the club went wild for the three former teen stars.
