Kelly Rowland was all smiles as she paraded her post-baby body while shopping for groceries following a workout on Tuesday.

The former Destiny's Childs member, and Beyonce's BFF, was still wearing the Nike tracksuit that she wore for the workout when she was potted during the outing. Kelly Rowland just gave birth to her baby boy with Tim Witherspoon, Titan, on November 4.

She also wore a pair of sunglasses and Nike trainers to complete the look.

"And an onlooker tells MailOnline that when the stunning star was asked by a fan what her New Year's resolution was, she responded by saying that she'll be working on making her 'butt look good," the article said.

The year 2014 has been a roller coaster ride for Kelly Rowland. She married long-time sweetheart Tim Witherspoon in May in an intimate wedding in Costa Rica. A month later, they announced that she's pregnant by posting on Instagram a pair of baby Air Jordans.

Last month, Kelly Rowland gave tribute to her mother, Doris Garrison, who passed away at the age of 66 in her hometown in Atlanta, just a few weeks after Kelly Rowland's baby Titan was born.

In a statement released to the media following her mother's death, Kelly Rowland said: "It is with deep sadness that I announce the passing of my mother. She was an incredible soul who made countless sacrifices so that I could become the woman - and now mother - I am today. We humbly appreciate all the love and support and only ask for privacy during this difficult time."

Kelly Rowland's baby Titan has apparently become her source of hope amid the devastating loss. Beyonce's BFF has also been very protective of her son as she refused to show his face in various Instagram posts.

About a week ago, she posted a photo of her carrying her son with his face on her chest and her back to the camera. She captioned the image: "Simply having a wonderful Christmas Time."
