Rosario Dawson Denies Engagement Rumors

After rumors surfaced that Rosario Dawson was engaged to DJ boyfriend Mathieu Schreyer, the RENT actress says they are dating, not planning a wedding.

"Oh my God, I'd be getting calls from my grandmother being like, 'Mija! How come I had to read this first?' " Dawson, 29, told PEOPLE at a New York bash in honor of the 2009 Audi A4. "Believe me, no."

Dawson and Schreyer, who have been dating for less than a year, heated up during a European vacation this summer. They've also been spending time together helping with voter drives for next week's election.

Schreyer hasn't been the only man in Dawson's life recently. For her upcoming movie Seven Pounds, she's reuniting with Will Smith, her Men in Black II co-star. The flick tells the story of Ben Smith, an IRS agent who helps seven strangers.

"Will's amazing," Dawson said. "It's a tearjerker movie. If you buy a ticket to this movie, make sure you get a box of tissues with you."
