Jane Fonda Co-Star Timothy V. Murphy – She's a Legend ... At Sucking Face!

EXCLUSIVE

Timothy V. Murphy has no problem with kissing and telling… at least when it involves the iconic Jane Fonda and her ageless mouth. 

Our photog caught up with the "Sons of Anarchy" star to get the deets on his intimate scene with Jane on her new Netflix show, "Grace and Frankie."   

Yeah, she's 77, but Timothy couldn’t wait to tell us why he'd put Jane's lips -- and tongue -- up against any chick in the biz. 

Two things put her over the top in his book -- experience and size. Check out Tim's explanation.
