Nicki Minaj, who recently was reported having "steamy sex affair" with Zac Efron, took to Twitter to address the issue. "Who exactly is Zac Efron tho? I'm sorry, I'm so confused," the 30-year-old rapper wrote in a Twitter post, as quoted by Gossip Cop. The Twitter post was later removed.

A fan reportedly replied her tweet, sending a photo of a shirtless Zac. "Oooohhhh ok... Well I guess that rumor isn't so bad after all. lmfao," she wrote again.

Previously, Star magazine romantically linked the "Starships" singer to the 25-year-old actor. "Zac and Nicki shared a steamy night together. Nicki took Zac to her house in West Hollywood. She said he was the best lover she's ever had," a source told the magazine.

Zac was recently said having completed a rehab stint for substance addiction. Zac, however, did not say anything about the rehab report. Speaking to Chicago Sun-Times recently, the "Parkland" star told the news outlet that he was in a good place.

"I'm doing what I set out to do. You have to go for it. You have to try. I want to challenge myself with tough parts. I wouldn't want it any other way. As an actor, my goal has always been to continue to challenge myself and learn and grow as an artist. I've been very lucky to have the chance to work alongside of great actors and directors. I couldn't ask for anything better," he said.
