Rose looked equally excited to spend some quality time with her little one, and tried to be incognito in a blue blouse, denim jeans, brown knee-high boots, a cap and sunglasses.
Rocco, 2, was ready to play in sweatpants, sneakers, and a shirt that had an image of popcorn.
In addition to Rocco, Rose and Bobby also welcomed a son last year, but the very private couple has yet to disclose his name.
After Rocco's birth, Rose gushed about him, and admitted he is "pretty mellow," adding "he's cute...He's got a big fat head."
Rose's co-star at the time, Susan Sarandon, also spoke about him after meeting him, and said, "He's so cute, and so masculine," noting that he had big eyes.
