Another day, another 'Hills' engagement!

Almost a month after Lauren Conrad became engaged to boyfriend William Tell, her former co-star Whitney Port also has some exciting news to share: She, too, is off the market!

Port, 28, is set to marry boyfriend Tim Rosenman, her rep confirmed to PEOPLE. Rosenman, who has been dating the fashion designer since 2012, was an associate producer on Port's 'Hills' spin-off, 'The City.'

"She is super comfortable with him and in love," an Us Weekly source revealed.

No word on any wedding plans as of yet, but it doesn't look too likely that Port and Conrad will be sharing any tips or tricks with one another.

"I think we all kind of went our separate ways once the show ended," Port, who also mentioned that she sees Conrad "here and there," told PEOPLE in 2012.

"I'm fine with it, like I'm at peace with it," she continued. "With me, I never feuded with anyone, and nothing ever ended badly, so it just naturally happened."

While they may not be planning their dream days together, we're sure that both designers' simple-but-elegant style will make for two classy and beautiful weddings.
