(Cover) - EN Showbiz - Hayden Panettiere is feeling frustrated because her boxer boyfriend wont teach her to fight.

The American actress has been dating Wladimir Klitschko for around a year, and they are very happy together. Wladimir is a Ukrainian heavyweight boxer, and Hayden is desperate for him to impart some fighting skills. He has given her a few tips, but refuses to get drawn when she tries to spar with him.

All he taught me was, Dont ever punch anybody with a closed fist because youll break it. Thats it! I was like, Come on! Youve got to teach me! Lets mess around! hitting him with playful punches and hes like, Will you stop hitting me. Why does everyone always want to hit me? she laughed.

Wladimir is 6ft. 6ins, while Hayden is only 5ft. 1ins. She doesnt see a problem with their differing heights, insisting it has actually helped their relationship become strong.

We dont notice it any more. A lot of relationships are always physically close, being all lovey-dovey, but with him being so much taller, Im forced to take a step back and have a conversation otherwise I get a sore neck, she told Look magazine. So theres more eye contact, which I think makes it a very balanced relationship. (C) Cover Media
