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."
