Buffalo Bills defensive back Duke Williams was left red faced when Lebanese porn star Mia Khalifa revealed to her Twitter followers that she rejected his advances.

Khalifa suggested on Twitter that Williams tried to arrange a meet-up with her, but she knocked him back by informing the sportsman that she is in a relationship.

The adult film star posted a screengrab of Williams's direct messages and added the caption: "Warning: Trespassers in my DM's will be shot and hung out to dry in public."

Williams responded to her public blast by writing: "Shutting this down NOW & FINAL...The full conversation wasn't posted. It was ONLY an invite to a pool party & PG. Other people were invited as well. There's no third or trespassing here. Trust that I am very hydrated #realtalk."

The 24-year-old joined the Bills in 2013.
