Katie Holmes isn't ready to date again.

While the 34-year-old actress - who split from Tom Cruise last year - has been linked to her 'Mania Days' co-star Luke Kirby, she reportedly doesn't want a relationship right now and is trying to prioritize her seven-year-old daughter Suri.

A source told People magazine: ''She's lying low on the romantic side of things. She doesn't need that right now. She's just focusing on her daughter Suri.''

However, the 'Dawson's Creek' star has such visible chemistry with her on-screen love interest, that eye-witnesses on the set of the indie drama are convinced the pair are secretly a couple.

A source told America's OK! magazine last month: ''The word on-set is that they are hot and heavy - you can totally tell the chemistry between them. Katie obviously has it bad for Luke!

''They're desperate to keep the state of their relationship under wraps until it's at least had a chance to start.

''Luke's a total gentleman who always puts others first. He's also incredibly handsome, charming and completely down-to-earth. Katie adores him.''
