Audrina Patridge is getting the hang of this motherhood thing. On Monday, the former "Hills" star shared a snap of herself breastfeeding her 3-month-old baby girl, Kirra.

The image, she said, was actually captured by her younger sister Casey Patridge Loza.

"@caseyloza always capturing me in moments," Audrina captioned the pic of the mommy-daughter moment, adding the hashtag "mom on the go."

The photo was actually taken last week, with Casey using the hashtags "casual breakfast #she makes breastfeeding look cool."

The photo shows Audrina wearing a Jack Daniels t-shirt with ripped off sleeves. She looks off in the distance while holding her baby girl in her lap.

On June 24, Audrina welcomed her daughter with fiancรฉ, Corey Bohan. She often writes about Kirra and motherhood on her website.

"As a new mother, I'm learning a lot of new things along the way. I am by no means an expert at caring for a baby, but I was pleasantly surprised by the amount of maternal instincts I had when Kirra arrived! But, instincts can only take you so far," she wrote earlier this month. "Corey and I were lucky enough to have friends and family who were willing to help us out with baby-related questions."

"We are so incredibly lucky! Kirra is the happiest, most beautiful baby with a constant smile and lots of goo-ing and gaa-ing!" Audrian wrote on August 24. "She loves giving Corey and I the biggest smiles, but I can't wait until she giggles the first time โ€” right now she gives lot of expressions but no noise. She sleeps 6-7 hours a night (only waking up once or twice) and is pretty laid-back (unless of course she's hungry, has to burp, needs a diaper change or gets restless!)."

She continued, "I absolutely love being a mom โ€” Kirra is my number one priority. If I'm being completely honest, the first month of no sleep, C-Section recovery, unpacking, and getting back into the swing of things was pretty grueling. But, at the end of the day, all I had to do was take one look at Kirra and none of that mattered anymore."
