Enjoying a break from her busy Broadway schedule, Ashlee Simpson joined husband Pete Wentz and little Bronx Mowgli for a winter outing in New York City on Wednesday (December 9).

Not letting the cold and windy weather deter the day’s plans, the happy family made their way to a nearby playground in Manhattan for a little time on the swingset to go with a walk around their Big Apple neighborhood.

As previously reported by Gossip Center, Ashlee just recently kicked off her stage duties for “Chicago”, in which she plays the character of heart-stealing jailbird Roxie Hart.

With shows running through February 7th, Miss Simpson wrote to fans on Sunday, “Woo first week of CHICAGO..It’s so warm and fuzzy there! The cast has made me feel at home.. LOVE! Thanks to the peeps comin to the shows!x”

Jessica Simpson is coming to her family’s defense once again.

The 29-year-old singer — who called Melrose Place “crap” after her younger sister Ashlee was canned — is now going after celeb blogger Perez Hilton, who poked fun at her nephew Bronx.

On Friday — Bronx’s first birthday — Perez wrote: “It’s been one year since Asslee pushed Bronx Mowgli through her vayjayjay and it’s all the family is talking about!”

He then ended his post by calling Bronx a “poor lil’ thing” who “doesn’t stand a chance!!!”

Simpson wasn’t amused. She Twittered later that day: “Does perez hilton..whatever his name really is..have no heart at all?Don’t ever attack my family again.Sad to know u hate so deeply.Sad 4 U”

Her spirits seemed to improve a short time later. “I challenge everyone to save up for a flt [ed note: flight] to somewhere you have always wanted to go. Get inspired beyond boundries [sic],” she wrote. “Find something waiting!”

Ashlee Simpson and Pete Wentz celebrated son Bronx Mowgli’s first birthday with a SpongeBob-themed celebration at grandparents Joe and Tina Simpson’s house in Encino, Calif.

About 30 family and friends, including aunt Jessica Simpson, arrived around 12:30 p.m. on Saturday for a bounce house, cake, the singing of “Happy Birthday” and a surprise appearance by the cartoon character.

Wentz, 30, told PEOPLE last week that Bronx “likes Bob and he likes guitar – which he calls ‘itar,’ so we’re going to have a SpongeBob party for him.”

The party went well, according to Wentz, who thanked party planner Mindy Weiss and others on his Twitter page Saturday night for the “rad b-day for bronx.”

Bronx’s actual birthday was Friday, and the night before, mom Ashlee and aunt Jessica Tweeted their birthday wishes. Ashlee wrote, “BX’s 1st bday tomorrow! My angel is going to be a year!! The greatest year of my life ”

Jessica added, “Happy Birthday to my precious angel on earth!!! Bronx is 1 today!! I LOVE HIM SO MUCH!!! I can’t believe it has been a year already.”
