First her breasts and now her face? Since breaking up with baseball star Alex Rodriguez last year, Cameron Diaz seems to have gone out of her way to prove she is young, carefree and single!

Cameron will be turning 40 in August, and RadarOnline.com has new photos that suggest she has gone to extremes to turn back the clock before her landmark birthday.

"There's something about Cameron Diaz's face that is very unusual," celebrity plastic surgeon Dr. Anthony Youn, who has not worked with the star, told RadarOnline.com in an exclusive interview.

Justin’s brought sexy back into his life!

Justin Timberlake and Jessica Biel were snapped taking a leisurely bike ride together in Toronto over the weekend and RadarOnline.com has exclusively learned the former exes are romantically back together again.

“They decided they wanted to be together and they’re happy again,” a source close to the couple told RadarOnline.com.

Alex Rodriguez can play baseball with the best of 'em, but he can't play Cameron Diaz.

Things have heated up between the Bad Teacher stunner and Yankee third baseman, who've been dating for a year-and-a-half, since Diaz pulled off a brilliant gambit to show the baseball slugger who's in charge.

Here's how it all went down: 

An insider close to the couple tells the new issue of Star that "Alex and Cameron broke up briefly this spring because he kept waffling on settling down with her and he complained she was getting too clingy and that he needed space ... [so] Cameron tried a little reverse psychology on A-Rod."

He’s shined on Star Search, saw ya real soon on the Mickey Mouse Club, got N'Sync with platinum records, brought sexy back and poked Facebook on the silver screen.

Now, Justin Timberlake's taking a break.

The multi-talented Memphis native told Jay Leno on Thursday’s Tonight Show that he won't be filming any movies or recording any music for the rest of the year, just promotional work for the stuff that’s already in the can.

You can’t say Cameron Diaz doesn’t work hard for her money! The sexy star has been busy promoting her latest movie Bad Teacher across the globe hitting photocalls, red carpet premieres and other promotional events in smashing fashion and RadarOnline.com has all of the photos and details about her stellar style.

Cameron Diaz has one of the most talked-about bikini bodies in Hollywood.  With her amazingly toned arms, long and slender legs and rock hard abs, the former model can rock the skimpiest bikinis to perfection -- and she does!

RadarOnline.com is honoring the blonde bombshell, whose latest movie Bad Teacher hits the big screen on Friday, with a special, stripped-down photo feature.

Though Cam was obviously blessed with superior genes, the SoCal native still has to break a sweat to maintain her perfect-10 bikini bod, but all that hard work has paid off over the years, because Cam looks just as amazing at 38-years-old as she did ten years ago.

Bob Marley would have been proud.

Actress Cameron Diaz, promoting her new film Bad Teacher on Tuesday's Late Night with Jimmy Fallon, had this message to share with America: "Weed is Awesome!"

Diaz, 38, was telling Fallon about her racy character in the film, a wayward junior high teacher named Elizabeth Halsey.

According to Diaz, Elizabeth is obsessed with getting a boob job, drinks on the job and encourages another teacher to get high.

Cameron Diaz appeared on The Late Show with David Letterman on Monday, and told the Indiana funnyman she’d give him “an exclusive” on why she fed her baseball slugger boyfriend Alex Rodriguez popcorn at this year's Super bowl.

It was this past February in Arlington, Texas where Diaz, 38, was famously caught on camera feeding her Rodriguez popcorn, as they watched the Packers and Steelers go at it.

Diaz told Letterman that when A-Rod went in for one of the final pieces of the movie snack, Diaz got protective of her popcorn, but then had a change of heart, telling the Yankee third baseman, "I love you too much, I'm gonna give it to you, you deserve it," and feeding him (as the world watched on).
