It seems like Britney Spears has been doing her darndest to fulfill her New Year's resolution to "take care of me more," focusing firmly on her own needs and wants (keep reading for details about her new slab-of-beefcake beau). But on Wednesday afternoon, she sacrificed some me-time to remind son Sean Preston what she looks like in the daylight.

The PR-battered pop starlet, who stepped out in a surprisingly presentable ensemble of a loose print dress and brown suede boots, brought the chubby-cheeked 16-month-old along to a Bel-Air pet store, where SPF mimicked his club-hopping mommy by taking a few wobbly steps forward, a milestone event captured by the ever-present paparazzi.

Despite being voted the worst celebrity dog owner of 2006, Britney exited the store snuggling a quivery, pink-sweatered pooch that bears a striking resemblance to her jettisoned Chihuahua Bit-Bit (hard-working manager Larry Rudolph carried Sean P).

And while four-month-old Jayden James remains under wraps (and hopefully in the loving embrace of a highly trained, well-compensated caregiver), another new man in Spears' life is getting plenty of attention.

People reports she's been "cavorting on land and sea" with a model-actor named Isaac Cohen, a Kevin Federline look-alike (yes, we're chilled by the thought, too) who shares his predecessor's predilection for bandanas, carefully sculpted stubble and baggy, saggy, skivvy-revealing jeans.

Spears, 25, who was snapped locking lips last month with music producer J.R. Rotem, was first spied with Cohen, 25, during her sleepy New Year's Eve celebration in Sin City. A bikini-crammed boating trip off Marina del Ray followed on Jan. 6, along with a smooch session at an L.A. club a couple days later (per Perez Hilton).

Cohen's likely elated modeling agent assures People that he "is not a player," and deftly positions him as the Bizarro K. Fed: "He's got a great heart and a good family, and he was raised well. He's a gentleman."

So what does this gentleman prefer, besides blondes with a self-destructive streak?

"living, duuurtt bikes, 4 Wheelin', kung fu flicks, rappin', slappin', tappin'. ya know?!!?" he eloquently shared on his now unavailable MySpace page (per Star).

(And suddenly, Federline's raps don't seem so bad.)

Anyhoo, the model's other interests include "The Family Guy" ("ohhh and i love taffy! i am a man who loves his taffy," he penned in an homage to the comedy. "mhmmm mhmmm mhmmm mhhmmmm!") and dates who act their age ("I get tired of girls who are 21 going on 15 ... and 13-year-olds going on 30 ... it's time to grow up people ... that is all").

But even though his recent Britney association has upped his profile, Isaac "is not out to get a name for himself," his agent vouches to People. "He's not just a pretty boy."

Speaking of pretty, Britney's stylist (yes, we're chilled by the thought, too) is evidently trying to put a Grand Canyon-size distance between herself and her Mr. Blackwell-slammed client.

In Touch claims the put-upon fashion maven is kvetching over being connected to the tabloid staple, whose typical sartorial statement is, "I'm disheveled, y'all!"

"Yes, I've done Britney Spears, but don't blame me, okay?" the stylist supposedly sniffed at a December soiree. "I make her up and she just takes everything off and does her own thing."
