Alessandra Ambrosio showed off her fit figure while celebrating the world's best sport bras for Victoria's Secret. The VS angel posed for the lingerie giant in Los Angeles on Thursday, flexing her muscles for the cameras.

Earlier this month, rumors surfaced that she split from her fiance Jamie Mazur. A rep slammed the gossip, saying, "It's not true, they are still happily together."

The couple got engaged in 2008 after three years of dating. They have two children, daughter Anja, 5, and son Noah, 17 months.

Meanwhile, Ambrosio, 32, is gearing up for the 2013 Victoria's Secret Fashion Show, which will air Dec. 10. Pal Candice Swanepoel will wear the Royal Fantasy bra worth $10 million.
