Clearly, the country has become enamored with this year's Best Actress winner
, Jennifer Lawrence
. And if Bradley Cooper
wasn't charmed by her already, now he has plenty to love about her.
"I feel like all I've been doing lately is setting him up," Lawrence, 22, told MTV
of her Silver Linings Playbook
But interest in the actor (PEOPLE's Sexiest Man Alive
in 2012) is so great that the actress has had to strategize.
"I was like, 'You know what? I'm going to save time, I'm going to get you a booklet of pictures of my friends and you just go through and pick them out,' " she joked. "Because this is getting exhausting for me."
Though he plays her love interest in their romantic comedy, the sparks between them are onscreen only.
Says Lawrence, "He's my brother."
