Gabrielle Union is showing off that fabulously fit body!

The "Think Like a Man Too" star was spotted in a tiny black bikini as she hung out by the pool at Wynn's Encore Beach Club in Las Vegas this week. She completed her look with blue-tinted aviator sunglasses and kicked back with an ice cold drink.

So, how does the 41-year-old actress stay in shape?

Gabrielle said that she eats a well-balanced diet and has somewhat of a sweet tooth, so she allows herself occasional treats. Moderation and portion size are her "secret" weapons to staying slim.

"With her body, she's a natural athlete," Union's trainer, Ahmad Baari, told Us Weekly. "Depending on her schedule we'll do about three or four months that I will see her regularly, she'll leave and then come back and we work to get her back to where she wants to be. She tells me exactly what she needs."

The brunette bombshell is engaged to Dwyane Wade. The happy couple has been dating since 2009, and the Miami Heat star hasn't been shy about expressing his love for the stunning star.

"She makes my eyes sparkle," he told Oprah Winfrey last summer. "The biggest time she makes my eyes sparkle is when Zaire (his 11-year-old son from a previous marriage) comes home and homework is a little hard that day, so he's stressing, and she goes to the table with him and she sits down until he gets it."

"And at that time my heart is smiling a little bigger that day because I know her love is deeper than just me," he said.

Too cute!
