You may think that rich and famous would go all out when it came time to celebrate their birthdays. Well, apparently not all of them do! To ring her seventeenth birthday last week, mommy-to-be Jamie Lynn Spears and what's-his-face celebrated with a little shopping and dinner. No, the two didn't exactly hit up Saks and dine at five-star restaurant. Instead, the couple hit up Wal-Mart and feasted on some Ruby Tuesdays. Turns out the starlet is just like everyone else who just can't get enough of those "roll-back" prices and all-you-can-eat salad bars?!
