Hayden Panettiere has revealed her fans ask her about her sex life with her boxer boyfriend.

The diminutive actress - who stands at just 5ft 1in tall - is in a relationship with world heavyweight champion Wladimir Klitschko, who at 6ft 6ins towers above her.

A stunned Ellen responded by saying: "I know what you're talking about, but I'm in shock!"
