Applegate on People's 'Most Beautiful' cover

The 37-year-old actress, who recently battled breast cancer, certainly has much to celebrate: She says she's finally found her "perfect type" in her new beau, Dutch musician Martyn Lenoble (Mar-TAN Luh-NOBLE).

Applegate had a double mastectomy last July and reconstructive surgery months later. The star of ABC's "Samantha Who?" calls Lenoble an "angel" who loves her "from head to toe."

According to Applegate, Lenoble has been her "rock" and gave her reason to live — and smile.

The annual "Most Beautiful" issue features 100 famous faces, including Michelle Obama, Zac Efron and Cindy Crawford posing without makeup. It hits stands Friday.
