Jessica Biel has joked she is ''creepily'' obsessed with Jennifer Garner.

'Butter' actress Jennifer presented Jessica with the Tiffany & Co's Luminary Award for her work with Charity: Water at Variety's annual Power of Women luncheon at the Beverly Wilshire Hotel on Friday (05.10.12) and in her acceptance speech, Jessica revealed her admiration for Jennifer.

She told Jennifer: ''You're one of those magical women who can be everywhere and do everything and make it all look so easy.

''There's a fine line between admiring someone and creepily wanting to actually be them. And I feel like I'm constantly walking that line with you.''

Meanwhile, Jennifer - who is married to Ben Affleck- paid tribute to Jessica's ''bawdy'' sense of humour and called her a ''girl's girl''.

According to E! News, she said: ''Her brand of humour is bawdy, much bawdier than you might even imagine.

''I know Jessica to be a true girl's girl. She's the kind of girl who will check that you don't have lipstick on your teeth and your Spanx aren't sticking out. She has got your back.''
