Robert Pattinson Girls Roundup: The Many (Supposed) Women Since Kristen Stewart Split

We break down all the lovely ladies the actor has allegedly hooked up with in the past four months

It seems like everyone desperately wants Robert Pattinson to be with somebody...anybody!

After all, in the four months since the 27-year-old actor split with Kristen Stewart, the guy has been romantically linked with a seemingly endless number of gals.

In fact, just this week alone, there's been speculation that he's moved on with not one, not two, but three different ladies.

So, we figured this might be as good a time as any to try and set the record straight about R.Pattz's love life (at this point).

Riley Keough: Tabloids began speculating in July that Pattinson was dating Elvis Presley's granddaughter after a woman bearing a striking resemblance to Keough was photographed with the Twilight star in his Silverado pickup truck. However, Keough's rep said there was no truth to the dating report, insisting it's impossible since she was not photographed the day the pic was taken. "Riley isn't dating Rob," a rep for the 24-year-old beauty told JustJared.com. "And I can confirm that Riley was not photographed at all this weekend," her rep added, confirming Keough was not the mystery woman in Pattinson's car.

Sia: Pattinson was seen with the 37-year-old Australian indie rock singer and songwriter grabbing drinks at L.A.'s Soho House in July, just two nights after catching the Jay Z and Justin Timberlake concert together. But a source exclusively told E! News at the time there's "definitely nothing romantic" going on between the two.

Sydney Liebes: Tongues started wagging this week that Pattinson may have found himself a new ladylove after being spotted leaving the gym with a mystery gal on several occasions, though ultimately driving off in separate cars. Well, E! News learned on Tuesday that the mystery woman was Liebes, a trainer who steps in to work with R.Pattz when his usual trainer Harley Pasternak is unavailable to meet with him.

Mystery Brunette at Party: Over the weekend, Pattinson reportedly stepped out with a new girlfriend to attend a pal's birthday party in Los Angeles. Sure enough, though, a source tells E! News that Pattinson is "not" dating "the mystery brunette."

Dylan Penn: Has Pattinson hooked up with the 22-year-old daughter of Sean Penn and Robin Wright? Well, that's what Life & Style is insisting in their latest issue, claiming the two got quite cozy at L.A.'s Viper Room earlier this month. But once again, a source tells E! News that this is simply not true, saying, "Rob and Dylan are just friends."

In fact, when it comes to all these lovely ladies, and Pattinson's love life in general, our source insists the actor is not dating anyone right now, stating, "Rob has no interest in dating anyone right now."

And there you have it. For now, at least.
