The funnyman and Wrecking Ball hitmaker have been friends for years, but multiple reports suggesting the two had been "hooking up" recently surfaced on Wednesday (16Sep15), and Cook was quick to brush off the gossip, telling E! News, "I'm always the last to know these things. Just let Miley know that I'll pick her up for dinner at eight."

Cyrus was most recently linked with Victoria's Secret beauty Stella Maxwell, while Cook's reported exes include Nicole Scherzinger and Julianne Hough.
