There's a new girl in town on The Big Bang Theory — and that might mean trouble for Leonard and Penny.
Despite her professional relationship with Sheldon, she sets her eyes on Leonard (Johnny Galecki), which may drive a wedge between him and Penny (Kaley Cuoco), according to the report. Executive producers Bill Prady and Steve Molaro told TVGuide.com earlier this summer that the couple is "on a very rocky road."
Sounds like it's about to get rockier!
The Big Bang Theory premieres Thursday, Sept. 27 at 8/7c.
