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**.
