The pair were spotted at the popular restaurant matching in similar outfits, with Roberts rocking a white T-shirt, plaid overshirt, dark jeans and shades, reported E! online.
Roberts also shared a few photos on Instagram on her birthday, including a shot of a beautiful bouquet of flowers and a wrapped present.
Unfortunately, Roberts' birthday came on the heels of the tragic news of her aunt Nancy Motes. She died of an apparent drug overdose on February 9.
