The new issue of the 'Star' magazine has a rundown of Hollywood's Best and Worst Lovers just in time for Valentine's Day. Yeah, it's based on hearsay from anonymous sources but you still want to hear what they have to say, right? Taylor Swift made the list, but for better or worse? 

The Best:

--JOHN MAYER is "sensational" in the sack.

--RYAN GOSLING has, "laser focus" while he's doing the deed.

--BEYONCÉ ties up JAY-Z and, "gets absolutely wild."

--JASON SEGEL is "amazing" during sex, then gets, "giddily goofy" afterwards.

--BRADLEY COOPER talks nonstop in French.

--BEN AFFLECK gives massages, puts flowers around the bed and puts a woman's needs before his own.

--BRAD PITT and ANGELINA JOLIE get freaky behind the waterfall in their pool.

--JENNIFER LOPEZ is a SCREAMER. In fact, a source says, "Once, in a hotel, a maid charged into her room, thinking she was being murdered."

--As for DEMI MOORE, a source says, "Her relationships don't end for lack of bedroom excitement."

The Worst:

--TAYLOR SWIFT isn't too exciting. A source says,"All she wants to do is kiss for hours, which is probably why none of the guys she dates stick around."

--JENNIFER ANISTON "just lays there."

(--Yes, this is an incomplete list. You have to buy the magazine for the whole thing.)
