Jennifer Lawrence went "full radio contest winner" when she met Ariana Grande.
The 31-year-old actress - who is expecting her first child with husband Cooke Maroney - was left starstruck by her 'Don't Look Up' co-star and couldn't contain her excitement when they met for the first time.
During a Q&A for BAFTA voters earlier this week, the 'Silver Linings Playbook' actress gushed: "She can't make bad music.
"I've since reflected on my behaviour with Ariana Grande. I went full radio contest winner."
And Jennifer admitted she knows she didn't act particularly cool around the 28-year-old singer.
She added: "I was so excited and nervous that at one point, I just kind of walked into her hotel room and sat down.
"I've just been thinking about it a lot lately. There were all of these trunks for her hair and makeup, and I was like, ‘Do you live here?'"

She gushed at the time: "Breaking f****** news. Jennifer Lopez and Ben Affleck are back together. They're in Montana. They are on vacation with each other right now.
