Popstar and actress Jennifer turned heads in the red knee-length Herve Leger number as fans greeted her outside the studios.
Jennifer, 45, always looks gorgeous, very rarely putting a fashion foot wrong - and this was no exception!
Showing off her curves, the mum-of-two looked pretty fierce as she walked into the studios while waving to fans.
And, making sure all eyes were on her, the 'Jenny from the Block' hitmaker teamed her vibrant dress with pointed red heels.
Letting the dress do the talking, Jennifer's long locks were tied in one flowing behind her back.
We love it!
Mum-of-two Jennifer was joined by her fellow American Idol judges to talk about the new series of the hit talent show.
