Brad Goreski is getting married.

The newest "Fashion Police" panelist is engaged to his longtime boyfriend of 13 years Gary Janetti, a well-known writer and producer. Goreski, who rose to fame as celebrity stylist Rachel Zoe's former assistant on Bravo's "The Rachel Zoe Project," revealed the exciting news exclusively to E! News at TrevorLive LA.

"We got engaged in August," Goreski told E! News. "He had to go to London so wedding plans are on hold. My fiancé is working there right now and he's going to come home for Christmas. Then we're gonna go back there. I'm a bridezilla already! Who's gonna design my gown? The big question already."

Goreski recently signed on to join Kathy Griffin, Kelly Osbourne and Giuliana Rancic in E!'s Fashion Police following the death of host Joan Rivers. Janetti is currently working on the popular British show "Vicious."

This summer, the couple returned the Greek island Mykonos to revisit to the area where they first met. Goreski posted a picture of himself and his fiance on Instagram, with the caption, "Back to where it all began! Having the best in Mykonos with @GaryJanetti! #Greece #Holiday."

Goreski told the Huffington Post that Janetti is "very, very funny and also, so easy to live with." "There are way more things that I love about him than things that drive me crazy," he added.
