Wiz Khalifa and Amber Rose are known for their over-the-top public displays of affection, but they took it to a whole other level last night on Twitter.

Amber is currently away working on her debut studio album and has left boyfriend of one-year Wiz alone in their shared apartment. It's no surprise that they are missing each other, but perhaps they should have had a private conversation rather than share their affection on Twitter.

28-year-old model Amber started it off, writing: "@RealWizKhalifa I miss u monkey :-(," to which Wiz responded: "@DaRealAmberRose i miss u too sweety so much my heart hurts. come home already!!!"

However, Amber took it to a whole other X-rated level, adding: "Ahh I Love u so much! I can't wait to get sticky with u & have u make a mess on me Be home soon Daddy ;-)"

Amber recently released her debut single 'Fame,' which features Wiz.

Save it for the bedroom guys!
