Bruno Mars: I hope Bieber hooked up at VS show

Bruno Mars "hopes" Justin Bieber hooked up with a model at the Victoria's Secret Fashion Show last week.

Both singers performed at the luxury lingerie's catwalk extravaganza, held at Lexington Avenue Armory in New York City.

Justin was spotted posing with a host of the gorgeous Angel models at the after-party and pop pal Bruno hopes the 18-year-old got lucky with the ladies.

"No, I didn't hook up with any models," Bruno laughed to Australian radio hosts Kyle and Jackie O.

"I didn't get a chance to see Justin Bieber, I was backstage rehearsing. I didn't see any action, I hope he did [hook up with a model] though!"

Bruno performed his latest hit Locked Out of Heaven, taken from his new album Unorthodox Jukebox.

Despite enjoying the show, the 27-year-old feels he has worn himself out with work commitments lately.

"I've been busting my ass!" he admitted.

"My voice is not in the best shape... [But the Victoria's Secret show] was awesome. [We did] a lot of rehearsals. Another reason why I'm probably hanging on limbs!"

Rumours were rife last week that Justin had struck up close friendships with some of the models at the fashion show.

Sources at the after-party, which was held at New York nightclub Avenue, say the Beauty and a Beat singer was asking models for their numbers and sitting with gorgeous Angel Miranda Kerr.

On Friday, E! News reported Justin and 20-year-old girlfriend Selena Gomez had allegedly called time on their relationship.
