X Factor star secretly dating Hollywood A-list actor

Well this has to be the most random, unexpected coupling ever!

X Factor fans will no doubt remember Katie Waissel, the controversial contestant who made it to the finals with One Direction in 2010?

Well, it looks like she has found love with an A-list Hollywood star!

Yes, Katie has set tongues wagging after it was revealed that she is secretly dating The Big Bang Theory actor Johnny Galecki, who plays Leonard on the hit show.

A source has told Now magazine that while the pair have only been on a few dates, it looks like romance has blossomed.

“They have been seeing each other for a few weeks now and it’s going really well. Johnny is really private and Katie isn’t one to splash her love life around so they have been keeping a low profile,” said the source.

Did not see that one coming!
