Ashlee Simpson & Her Barefoot Bronx

Ashlee Simpson and husband Pete Wentz were all smiles as they left CVS Pharmacy with a new truck for their son Bronx, whose first birthday is coming up on November 20.

Mom Ashlee, with her newly dyed black hair, seemed to be in great spirits despite the drama surrounding her recent departure from Melrose Place.

Proud dad Pete recently told PEOPLE that becoming a parent has really helped him to appreciate his own father:

It makes me realize all of the little things that my dad sacrificed when he had me. It’s sad it took 30 years but I totally realize it now.
