Tyra Banks and Bow Wow can't keep their hands, or should we say lips, off each other!

The 39-year-old supermodel and the 26-year-old rapper were both on BET's 106 & Park yesterday, where they reenacted some lip-locking PDA from their pasts.

"We have serious history," Banks said to the audience. "He had a little crush on me and was hitting me up on Twitter nonstop. I think he was talking about wanting to know what my lips taste like and stuff."

Banks then played a video of when she let Bow Wow give her a kiss back when he visited her on The Tyra Show. In the spirit of their PDA past, Banks then proceeded to lay her legs across Bow Wow's lap before giving him a sweet smooch as the audience went crazy.

After the show, Bow Wow posted a video on Instagram with the caption, "TYRA KISS MY LIPS TWICE." "Tyra touched these lips!" he screams excitedly in the clip. Banks also teased on Twitter before kissing Bow Wow on the show, "These stand 4my name or Tyra&BowWow? @106andPark 2day shud give u answer." In the twitpic, Banks shows off her T and B initial earrings, which she was wearing during the kiss.

Tyra also stopped by Jimmy Fallon's late-night show this week to promote America's Next Top Model and teach Fallon how to pose seductively pose the camera. The two got superclose, hugging each other and getting awkwardly sexy for an imaginary photo shoot (LOL!). However, there was no Fallon-Banks lip-locking during the visit.
