JENNIFER LOPEZ AND JAMES CORDEN TEXT LEONARDO DICAPRIO DURING CARPOOL KARAOKE

The best carpool yet?

Jennifer Lopez joined James Corden for Carpool Karaoke during his CBS primetime special Tuesday night, and it was nothing short of magical. They sang hits like “Love Don’t Cost a Thing,” “Jenny from the Block,” and “Locked Out of Heaven.” And she taught James a thing or two about how to pull off the dance moves in a music video.

She also talked about her five–FIVE–proposals, and gave him some great advice on how to turn people down.

“You just say no,” she said.

As an added treat, James hijacked JLo’s phone and texted Leo himself, saying “Hey baby, I’m kind of feeling like I need to cut loose. Any suggestions?”

Leo’s response is actually the best.
