These two definitely don't have to lose any more pre-wedding weight!
"American Idol" alums (and engaged duo) Diana DeGarmo and Ace Young celebrated their joint bachelor/bachelorette party this weekend in Las Vegas -- where they showed off their impressive beach bods by the pool.
The two were seen partying at The Palazzo Las Vegas' Azure Luxury Pool's grand opening, where both flaunted some serious skin (and tight stomachs) while celebrating with their friends.
How great does Diana look in that bikini? She'll make a gorgeous bride!
Young and DeGarmo, who got engaged on live TV during the Season 11 finale, are set to tie the knot this June in Los Angeles.
