Britney, Confused Sean Preston Purchase Pooch

She and Isaac Cohen may be hitting it off, but earlier this week, he was nowhere in sight as Britney Spears spent the afternoon tooling around L.A. and visiting a Bel-Air pet store with her manager, Larry Rudolph.

Amazingly, little Sean Preston Federline, age 16 months, actually went with his party animal mother somewhere. Of course, he was carried by Rudolph, not by mom herself.

With Britney's recent antics, you knew it was only a matter of time until Sean Preston and Jayden James are started wondering who this crazy blonde is who shows up every couple of weeks is. See below.

Yup, we'd probably be wondering the same if we were Sean Preston. To think that all this time, we thought Kevin Federline was going to be the bad parent. Live and learn.

With Rudolph toting Sean P., Brit reportedly picked up a new dog, Snow White - for the price of $3,200. S-Dubs bears an uncanny resemblance to her previous pooch, Bit-Bit.

So let's recap here. She spends two months going buck wild and traipsing around L.A. commando style. Then Britney claims on her official site that she's ready to turn over a new leaf to direct her focus on work and family. But since then, all she's done is party more, wear ridiculous outfits and embark on a steamy boat ride.

Now, she's decided that since she's sitting at home bored all the time with nothing to do, she should really get a new dog - even though she can't even be bothered to hold her own child. Marvelous. Hopefully this new boyfriend striaghtens her out!
