Katy Perry is smitten -- and not by Russell Brand.

She fell for Irish lifeguard Stepehn Concannon and demanded he take his shirt off and show his buff body during his turn on 'The X Factor.'

Perry was a guest judge when the show went to Ireland to scope out talent there.

When Concannon came onstage Perry and fellow host Cheryl Cole seemed smitten.

When he told the panel he was a lifeguard. Katy replied: 'Honey, I'm drowning! Save me please!' Cheryl was serenaded by the lifeguard and then Perry ordered him to take his shirt off.

After he sang Perry told him she would only put him through to the next round if he took his shirt off.

He quickly obliged, leaving Cheryl, Katy and the female members of the audience happy.
