Jennifer Lopez Bikinis With Shirtless Casper Smart in Brazil (PHOTOS)

JLo's Best 'Idol' Looks
Check out the judge's many looks from season 11!
Talk about a hot mama.

Jennifer Lopez, 42, hit the beaches of Brazil on June 25, and looked red hot in a teeny white bikini. Playing in the sand with her 4-year-old twins Max and Emme, the American Idol judge took a much needed break from her South American tour, by soaking up the sun, and flaunting her toned bikini bod.

As J.Lo was catching up on some mommy time, her beau Casper Smart was nearby, and showing off his shirtless bod.

The 25-year-old back-up dancer, who began dating Lopez in November of last year, indeed joined in on the beach fun, as did Lopez’s parents.

It looks like actress/singer has nothing but love for Brazil, as she tweeted on June 24:

“Just landed in RIO!!!!! One of my fave cities in the world! #JLOVE!RS can’t wait to Dance Again with you!! #jloDanceAgainTour !”

Always working hard, Lopez, who is currently going through a divorce with Marc Anthony, is preparing to release a greatest hits album, titled Dance Again…the Hits which will drop on July 24 — her 43rd birthday.

The track listing includes:

1. “Dance Again” feat. Pitbull
2. “Goin’ In” feat. Flo Rida
3. “I’m Into You” feat. Lil Wayne
4. “On the Floor” feat. Pitbull
5. “Love Don’t Cost a Thing”
6. “If You Had My Love”
7. “Waiting for Tonight”
8. “Get Right” feat. Fabolous
9. “Jenny from the Block (Trackmasters Remix)” feat. Styles P. & Jadakiss
10. “I’m Real (Remix)” feat. Ja Rule
11. “Do It Well”
12. “Ain’t It Funny (Remix)” feat. Ja Rule & Caddillac Tah
13. “Feelin’ So Good (Remix)” feat. Big Pun & Fat Joe
14. “All I Have” feat. LL Cool J (Deluxe Edition only)
15. “Que Hiciste” (Deluxe Edition only)
16. “Let’s Get Loud” (Deluxe Edition only)

It looks like these bikini pics stiffen the competition for hottest singing reality show judge.

Though it’s uncertain if Lopez will return for a third season of American Idol, Britney Spears and Demi Lovato — the ladies from FOX’s other singing show, X Factor, sure look fierce in bikinis as well.
