Though the duo has been spotted out spending time together, Lizzy Caplan is setting the record straight about her relationship with Bachelorette costar James Marsden.
"He's just one of my best friends," the actress told PEOPLE at Showtime's Emmy Eve Soiree on Sunday. "He's one of my dearest friends."
But even if the pals were romantically linked, the Mean Girls star is quick to point out that she'd keep it a secret."I wouldn't tell you anyway!" she said of Marsden, who split from his wife of 11 years in 2011.
While it's unclear whether Caplan, 32, has a date lined up for this year's Emmy Awards, the first-time nominee plans to have a good time before the show. "I have a lot of friends coming to hang out. There will be food. And they will be drinking. I will probably get slightly annoyed and looking for a moment of quiet and solitude, which I will not get," she joked. "And in the car ride there, I will be very happy that all the people showed up to hang with me. It's awesome. The fact my friends want to come hang is really nice."
