We spotted Britney Spears taking her pet pooches to the veterinarian over the weekend with the help of her sons Sean and Jayden. The singer looked casual in plaid boxer shorts, a grey tank top and sneakers. Her sons were equally adorable in shorts and sneakers.

Spears is making headlines for something her ex-boyfriend Justin Timberlake said during his comeback concert at a pre-Super Bowl event on Saturday.  Before launching into "Cry Me A River," which he allegedly wrote in 2002 about Spears, the pop star told the crowd, "Sometimes in life, you think you found the one. But then one day you find out that she is just some b**ch!" He has since denied the "b**ch" in question was Spears.

We also spotted Ashley Olsen out and about with her pooch on Saturday. The fashion designer juggled her dog, a Starbucks coffee and a cigarette as she walked through New York City. She made sure her daschund was protected in the cold weather in a cute striped sweater.
