It's The Real Housewives of Orange County's Gretchen Rossi!
"VMA Fashionable @GretchenRossi great meeting you," Farrah tweeted on September 5.
Gretchen is basically the blonde version of Farrah. Even better? Gretchen is an aspiring singer who's performed with the Pussycat Dolls, so Farrah was probably able to get some tips for her blossoming music career.
Do you think Farrah might be auditioning for a role on The Real Housewives? Lord knows those OC ladies could use a switcheroo, and she'd be a great fit!
