Hollywood's New Single Ladies

Fresh off her divorce from Tony Parker, Eva Longoria bounced back in late January with a new man ten years her junior – Eduardo Cruz (Penélope's little brother). Together, the new twosome have yachted in Miami and canoodled publicly at West Hollywood's Chateau Marmont. "Starting over is hard to do," the actress, who turns 36 on March 15, Tweeted, "but life goes on."

Just a day after announcing her split from Joe Jonas, Ashley Greene tuned her attention to another musical brother, Kings of Leon bassist Jared Followill. The duo, who flirted the night away at New York's Avenue nightclub, sparked romance rumors after leaving Phebe's Tavern amp Grill together March 17. "Good food. Good friends. Great day," the unattached Twilight star Tweeted.

Days after announcing her split from Justin Timberlake, Jessica Biel emerged for the first time in more than three years as a single lady at L.A.'s Café Entourage, where she celebrated her younger brother Justin's birthday on March 12.

Since her split from longtime love Penn Badgley, Blake Lively has been linked to some of Hollywood's hottest guys, including Ryan Gosling and Leonardo DiCaprio. Though she's keeping things casual, one thing's for sure: this Gossip Girl is back on the market!

"Once I filed for divorce, we started dating," Christina Aguilera said of her relationship with Matt Rutler, whom she met on the set of Burlesque. And though she's said she's taking the romance slow, friends of the pop star are hoping things come to a halt following a string of disturbing incidents, including the singer's arrest in March along with her beau for public intoxication.

She may be headed to divorce court with Pete Wentz, but Ashlee Simpson is keeping things cordial and low-key on the home front for her 2-year-old son Bronx, who tagged along with mom during a recent grocery run.

After divorcing Ryan Reynolds, Scarlett Johansson quietly turned to pal Sean Penn, whom she bonded with over their mutual passion for post-earthquake relief in Haiti. Though her rep denies a romance, the actress dialed things way past platonic when she was photographed with her leg draped over Penn, who later accompanied Johansson on a Mexican vacation in March.

Though Vanessa Hudgens says she's still with ex (and ) Zac Efron, the 22-year-old starlet is relishing in her newly single life with BFFs Ashley Tisdale and Brittany Snow and a few fellas, including Journey 2: Mysterious Island costar Josh Hutcherson.

Looks like Olivia Wilde isn't wasting time! Since splitting from her Italian prince, the House M.D. bombshell has been keeping company with Ryan Gosling, whom she hung with at a post-Golden Globes party and brunched with in Cincinnati in March.

If anyone gets the last laugh, it's Taylor Swift, who recently bumped into ex Jake Gyllenhaal at a post-Oscars bash. Though their run-in seemed serious, the singer (and her merciless songwriting pen) moved on, enjoying a hockey game with Glee hunk Chord Overstreet.
