Diem Brown Gets A Little Baby Love: See The Pics

As she fights cancer, the MTV star is buoyed by a visit from her 'Challenge' pal Paula 'Walnuts' Meronek -- and her son Atlas.

As she continues to bravely battle cancer, Diem Brown got a dose of the best medicine possible: Last week, "Challenge" vet Paula "Walnuts" Meronek paid a visit and brought along a very special guest -- her adorable son Atlas.

While the two former MTV stars caught up and surely reminisced about old times, little Atlas couldn't help but steal a moment during the bonding session.

"Look who visited with @diembrown #atlas was being a little flirt...safe to say he has his first crush," the "Rivals II" champ wrote in her sweet Instagram shot. "So great seeing you. Keep fighting Diem! We love you so much:) #medgift."

Through all her trials and tribulations, Diem's spirit is stronger than ever, and she's staying focused on her biggest goal in life: becoming a mom.

"It's my personal perspective that you live as hard and as vigorously as you can," she told People. "My goals are something I believe in, because I believe I'm going to make it."

And as she continues to fight her battle, D's "army of caregivers" is growing stronger by the day. "Real World: San Diego" alum Jamie Chung also paid a visit, providing some comfort in her dear friend's road to recovery.

Keep Diem in your thoughts, and contribute to her fight on her MedGift page here.
