The one and only Jennifer Lopez, aka J.Lo aka Jenny from the Block, drove around singing karaoke on James Corden's "Carpool Karaoke" special Tuesday, and dare we say the singing wasn't even the best part?

The best part would have to be when Corden asked J.Lo to name the most famous person whose digits she has in her phone. Lopez listed off a few of her contacts (Demi Lovato, Chris Brown, Bradley Cooper, Cristiano Ronaldo, The Rock, Fergie and Iggy Azalea) before "The Late Late Show" host grabbed the phone and asked if he could send one person a text.

Naturally, Corden picked recent Oscar winner Leonardo DiCaprio -- because, obviously -- and he had a lot of fun with it.

J.Lo couldn't handle it.

And that was before he signed the text like this:

Greatest text ever? No. Not even close. That honor is reserved for DiCaprio, who allegedly texted back:

There you have it. Leo and his Pussy Posse Wolf Pack have you covered for all your club-going needs.
