Is Joe Jonas Dating Ashley Greene?

Supposedly Digital Spy reports that Ashley Greene (that chick from twilight) and Joe Jonas are (maybe) dating each other.

A few weeks back at the "Twilight's Eclipse Premiere" there were rumors and reports that Joe and Nikki Reed are supposedly dating. Now this this Joe and Ashley rumor is true, then Joe is keeping it in the family or series. I prefer him with Nikki if he dated a Twilight girl. Also if this true, at least he is dating someone his own age. Demi and Joe, were a bit odd and creepy. Might I also add, ILLEGAL!

The article reports:

"The Twilight star and the Jonas Brothers member were seen having dinner together recently at the Ivy in London. It was a very romantic night. They arrived separately and then left out (sic) by the back door where there were two vans with blacked-out windows waiting to ." a source said.

The insider added: "They looked like a lovely couple. They had a few drinks and were clearly enjoying not being hounded like they would have been in Los Angeles."

Two problems with this. A "source" said it and "whisk them away"? To me this sounds likes this was made up or someone reads too many romantic novels.
So....
