It's Auntie Ash!

Ashlee Simpson indulged in some retail therapy in West Hollywood on Thursday, and we guess she wanted a little alone time, because son Bronx and boyfriend Vincent Piazza weren't in tow for the spending spree. This blonde beauty is so on trend with all her fashion that we would die to sneak a peek at her purchases!

We wonder if she picked out any gifts for sister Jessica Simpson's new baby girl Maxwell?! We've yet to get a glimpse of the the tiny tot, but her Dukes of Hazaard mother is already making plans for her big debut. Reportedly, first baby photos were bought by People magazine for $850,000. Not too shabby for your first paycheck! Guess it pays - literally! - to be a celebrity baby.

Cha ching!

With that hat and those sunglasses, Ashlee's new man Vincent Piazza could almost pass for ex hubby, Pete Wentz!

The happy couple enjoyed a fun-filled day of shopping and lunching in Beverly Hills on Saturday afternoon with Simpson's 3-year-old son Bronx Mogwi, after spending last week at the hospital with big sis Jessica Simpson for the birth of her baby girl.

After Jess welcomed daughter Maxwell Drew last Tuesday, the proud aunt gushed to People mag, "Bronx and I are in love with Maxwell already!" Ashlee told People magazine about how excited she and her son, Bronx, are. "Jessica has wanted to be a mom since we were little girls and I couldn't be more excited for her and Eric!"

Looks like the 6-hour flight from Los Angeles didn't affect these two!

Last night Ashlee Simpson and her adorable son Bronx landed at JFK Airport in New York City, and the 27-year-old singer/actress was looking better than ever as she carried her three-and-a-half-year-old through the terminal.

Speaking of kids, when is Ash going to become an aunt? It seems like her big sister Jessica should be giving birth any minute now, right?

Ashlee Simpson was spotted leaving the Andy Lecompte salon in Beverly Hills on Tuesday afternoon, and Jessica's little sis was looking sexy and svelte when she strutted out the front door.

Ash smiled as she showed off her newly-bleached locks, and even though she's wearing tights as pants, who cares! When you look this good, you can get away with just about anything...

Arnold Schwarzenegger can NOT get enough of his green fleece!

We spot the actor/politician in it everywhere. We appreciate that he's going green in more ways than one -- both fleece color and re-using his clothes -- but since he's always working out in it we hope the jacket isn't too nasty!

Reduce, Recycle, Reuse ... Re-fleece.

Who knew these two lovely ladies were so tight? Ashlee Simpson and Nicky Hilton left the Sunset Marquis together ... arm in arm.

The single Ms. Simpson, looking picture perfect with her blonde 'do, has never looked better!

Ash and Nicky were at the Marquis for the introduction to the new jewelry line ... Lia Sophia Industrielle II Collection.

Too bad Ashlee didn't bring her rumored boyfriend Boardwalk Empire actor Vincent Piazza to the event? Perhaps she doesn't want to parade her new man around until her divorce from Pete Wentz is finalized.

Does this mean the divorce is off?

Proud parents Ashlee Simpson and Pete Wentz reunited on Friday to take adorable little Bronx out for a playdate in LA, and they looked so happy to be together!

The pair filed divorce documents in L.A. Superior Court in February, with Simpson citing "irreconcilable differences" and seeking spousal support, but it seems things have cooled down between them. There has been no mention of going forward with the divorce since its filing four months ago.

Simpson has recently been hard at work on her new tween clothing-line, which is a collaboration with big sis Jessica. Ashlee told WWD on her new venture, “My goal will be to design clothes that will help inspire young girls to express their personalities and creativity through fashion.”

Meanwhile Pete is rumored to be hooking up with vocalist Bebe Rex (she's working with the Fall Out Boy on his new project Black Cards) but we're still holding out hope Simpson and Wentz will rekindle their romance!

Listen to Pete's Black Cards demo, after the jump ...

Ashlee Simpson may have a 1-year-old son and a pending divorce petition from Pete Wentz, but the singer still finds time to enjoy her life as a 26-year-old.

On Tuesday night, Ashlee we spotted as she exited the West Hollywood eatery Dominick's with a girlfriend. She wore her usual Pete Doherty-inspired outfit, but had a very present smile on her face adorned with bright red lips.

Jessica's little sister recently revealed she is working on a new album. On May 12, Ashlee tweeted:

"Writing sesh on the balcony. My album doesn't seem so far away..."

With everything that she has experienced in her personal life within the past year, Ashlee must have some good material to write about!
