Is Gregg dating Debby and Pixie?

Now I'm going to keep this short and sweet for my girl Debby, cause I know she's totally sick of hearing this rumor. The buzz around town is that she's dating Wizards' Gregg Sulkin, but she's not alone. The gossip also claims that Gregg is two timing her with singer (and Joe Jonas's friend) Pixie Lott! It all started during a stretch when Gregg was seen at a few red carpet events close to Debby's side and then out to dinner at the Cheesecake Factory with Pixie. So that means he's dating both, right? Wrong. Gregg spills: "I'm single and available!" The truth is that Gregg hasn't lived in LA for long and doesn't have that many friends to hang with, which is why you see him with pals like Pixie and Debby a lot. And now, hopefully, this rumor will die for good!
