Hollywood's newest cougar Delta Goodrem has discovered yet another perk of dating a younger man — she has a permanent designated driver.
Delta, 26, was photographed enjoying a pre-theatre dinner with her 18-year-old boyfriend Nick Jonas in Los Angeles last night.
But while she sipped on a rum cocktail, Nick was forced to stick to iced tea as he is three years under America's legal drinking age of 21.
The couple didn't seem to mind Nick's enforced sobriety, holding hands and laughing as they dined with friends before going to see Les Miserables at a nearby theatre.
Delta donned a short blush-coloured dress and strappy heels, while Nick wore jeans and a blazer.
Delta was first seen holding hands with Nick in May, just weeks after she ended her engagement with Australia's Got Talent judge Brian McFadden.
Nick, who has vowed to stay celibate until he is married, has dated fellow teen star Miley Cyrus.
