Louise Roe is engaged to Josh Slack, her boyfriend of two and a half years, the British star's rep confirms to Us Weekly.

Slack, a 24-year-old Abercrombie & Fitch model, proposed using Roe's great-grandmother's aquamarine ring. The betrothed stars plan to choose a new engagement ring together.

In a July 15 interview with England's Fabulous magazine, Roe — who hosted the short-lived CW series Plain Jane — hinted she was ready for Slack to propose.

"Lots of my friends are getting engaged — they're dropping like flies!" the 31-year-old fashionista said. "My two older sisters are mummies and I'd love kids running around one day, too."

Prior to replacing Elle Macpherson on Fashion Star, Roe was best known in the U.S. for appearing on season 2 of MTV's The City alongside Olivia Palermo, Whitney Port, Erin Kaplan and Roxy Olin.
