Dianna Agron is reportedly being pursued by Tim Tebow.
A source told the New York Post newspaper: ''Tim has made no secret that he likes Dianna, and told her so, but she has remained faithful to Sebastian.''
Sources also tell the paper Dianna and Sebastian, 28, have recently split again, blaming the distance between them and work commitments.
Dianna, 25, lives in Los Angeles and Sebastian lives in New York and has been filming 'Political Animals' in Philadelphia.
A source said: ''She was always worried that he was cheating on her while he was away filming, but he never would.''
Devout Christian player Tim, 24, is also said to be a favourite of Katy Perry's pastor parents, Mary and Keith Hudson, who were said to be trying to line him up as a potential son-in-law in the wake of her split from husband Russell Brand in December.
A source said previously: ''Katy's mom firmly believes the best cure for heartache is to quickly fall in love again. In her mind, Tebow is the perfect guy for her daughter. He's handsome, charming, intelligent and above all, a good Christian.''
