Dangerous curves ahead!

Singer Alicia Keys showed off her fit form while on a romantic vacation with husband Swizz Beats.

The hip hop producer shared a pic of his 32-year-old wife's toned bikini body from the beaches of Rio de Janeiro, Brazil. And we have to admit -- the man has a lot to be grateful for!

Earlier this week, the Girl on Fire songstress and her husband, who turns 35 today, arrived in Brazil with their 2-year-old son, Egypt, to celebrate Swizz' birthday.

On Sept.9th, the lucky man tweeted, "My life partner have it all on point. "Cheers to her. 9/13/13 #brazil #bdayweek #virgo."

The Grammy winner is also slated perform at the Rock In Rio Festival, alongside Beyonce and Justin Timberlake. Sounds like a killer line up!
