Teen Mom star Catelynn Lowell debuts first photos of baby girl Novalee on Instagram

'Being your mommy is the best thing in the world!'

She's teased photos of baby Novalee's feet and fingers since her birth  on  January 1.

But on Tuesday, Teen Mom star Catelynn Lowell shared a series of photos of her two-month-old daughter, showing her bundle of joy's face for the first time on Instagram.

The 23-year-old reality star and her fiance Tyler Baltierra - who gave up first daughter Carly for adoption in 2009 - couldn't help but gush about their second child writing: 'Being your mommy is the best thing in the world.'

In one photo, Catelynn gave baby Novalee a sweet kiss on her cheek while holding the little one in her arms with a soft pink blanket.

'Being your mommy is the best thing in the world, you make my days brighter,' she captioned the cute mother-daughter snap.

Doting dad Tyler also took to his social media pages to introduce his daughter to the world.

Also on Tuesday, he Instagrammed a beautiful picture of Novalee, showcasing her piercing baby blue eyes.

'Our little tootie is almost 3 months! I seriously can't get enough of her. Being a father is the best thing that has ever happened to me, every time I look at that face I fall in love more & more #NovaleeReign #MyGirl'

In another baby picture, the Teen Mom OG star shared a snap of her baby girl taking a nap in a red and white cheetah print onesie.

'Our sleeping beauty #NovaleeReignBaltierra,' she commented.

In 2009, the engaged couple put their first-born child Carly, now five-years-old, for adoption and documented the emotional decision on MTV's 16 And Pregnant.

And for the upcoming series Teen Mom OG, Catelynn and Tyler chronicled their second pregnancy in front of cameras even sharing the moment they discovered the sex of their baby.

In July 2013, the high school sweethearts called off their five year engagement.

But in December, Tyler popped the question for the second time with a new engagement ring.

Fans will be able to witness Catelynn and Tyler's relationship and parenting skills unfold when Teen Mom OG premieres on March 23 on MTV.
