Katie Holmes jeans bell bottom flared leg wedge blouse creme beige sunglasses purse Bouchon Bistro necklace bracelet ring phone

While hubby Tom Cruise is in Miami filming Rock of Ages, Katie Holmes is taking advantage of her alone time ... grabbing lunch at Bouchon Bistro in Beverly Hills. Looks as though daughter Suri stayed home with a sitter. Lucky mama!

Wearing mom jeans, a loose-fitting top and aviator shades, the 32-year-old actress kept it casual. Such a natural beauty.

Speaking of keeping it natural, Tom's wifey recently opened up about the possibility of one day going under the knife. Katie tells People:

    "I'll have to figure it out. But I don't think I'm ever going to do my lips -- my sisters would kill me!"
