Kelly Clarkson’s romance with Brandon Blackstock continued to go public on Tuesday with a trip to The Cheesecake Factory at the Sherman Oaks Galleria, in Sherman Oaks, Calif.

A makeup-free Clarkson, 30, looked relaxed and casual in a floral-printed summer dress, while her 35-year-old beau donned sunglasses, a hat, a gray shirt and jeans.

The happy couple — who have been dating since last year — recently made their first public appearance together, in White Creeks, Tennessee, at an event to celebrate No. 1 hits achieved by country crooning husband and wife Miranda Lambert and Blake Shelton. (See the photo here.)

In recent months, the Grammy-winning singer has been vocal about her booming relationship with Blackstock, who is the stepson of country superstar Reba McEntire. In a recent interview, she joked: “He is ruining my creativity!”

Clarkson is coming off a strong year, professionally: Her hit single ‘Stronger’ reached number one on the Billboard Hot 100, and she also served as one of four mentors on the ABC reality-competition series Duets.

Clarkson’s new single, ‘Dark Side,’ was released to radio this month.
