Rihanna Hooking Up With Ryan Phillippe, Sexting Colin Farrell...

Rihanna is taking advantage of single life by getting steamy with a couple actor hotties.

The latest Rihanna relationship rumors don't involve a Hollywood hottie. They involve two.

Rihanna has reportedly been embracing her single-lady status by having sex with Ryan Phillippe and sexting Colin Farrell. Interesting that she chose a couple men with reputations for hooking up and breaking up to get the hots for...

According to Celebitchy, US Weekly revealed that RiRi and Ryan have been getting it on for quite some time now—they've just kept it pretty darn quiet. While one source told the mag that Rihanna totally blew off Phillippe when they met up at the Gucci/Roc Nation brunch in L.A. earlier this month, another said that wasn't the case at all. They actually spent the night together following the event. Apparently Rihanna just has awesome acting skills and pulled the "I'm so not interested" card as a cover. Nicely done, RiRi.

"She thinks he's hot," the source said. "They totally had sex. And it wasn't even the first time!" OK, OK. Calm down. "They initially hooked up when things were strained with [Rihanna's ex] Matt Kemp back in early December."

Phillippe recently called off his three-month fling with Amanda Seyfried, making a reconnection with Rihanna at the Bing's Two King charity event imminent. But still, the two are keeping their canoodling very hush-hush. "There was no PDA," a source at the party said. Are Ryan Phillippe & Amanda Seyfried Hooking Up?

Although, Ryan did attend Rihanna's 23rd birthday in Beverly Hills the next day. "They hung out a bit, but were discreet. It is still very casual," one source said. Another added, "Clearly they're keeping it on the down-low."

We're thinking the Ryan-RiRi situation is definitely not exclusive, since she's also been sexting bad-boy actor Colin Farrell. As The Sun reported, the two met before Christmas on Graham Norton's talk show and exchanged numbers. Since, Rihanna has been sending the Irish star plenty of flirtatious messages. Farrell wasn't sure what to make of the singer's overtly forward communication at first, but he's now over it and on board.

"Colin was taken aback by some of the texts," an insider said. But that didn't last long: "He reckons he might well be in there. They're both single, so why not?"

Rihanna is obviously enjoying her freedom to play the field. Will she tame either of her womanizing flames, or add another guy into the mix soon? We'll keep you posted.
