Let's hope she's a better mom this time around!

Teen Mom star Jenelle Evans is pregnant with her second child, and now she's showing off the beginnings of her baby belly on Twitter!

"Baby bumpppp. My little angel," she captioned the snapshot.

Although the pregnancy wasn't planned, the 21-year-old told MTV she understands why people will have a negative reaction to the news and wants to prove them wrong.

"I know a lot of people will say we're not ready or judge me from my past. I want to prove to everyone that I can do this. This wasn't planned, but it happened so we're taking it as we go. Courtland and I are happy and excited now. We have our own place, we're married, and we're both working. We know having a child can be difficult, but we're going to do our best," she said.

The newly married reality star's son Jace, from a previous relationship, lives with her mother Barbara.

Let's hope she sticks to her word!

Teen Mom 2 star Leah Calvert (formerly known as Leah Messer) is expecting her third child.

This is the 20-year-old reality starlet's first kid with husband Jeremy Calvert; she has two-year-old twins Ali and Aleeah with her first husband Corey Simms, whom she divorced in 2011.

"Jeremy and I are excited to be adding a new addition to our family," Calvert said in a statement. "Being a teen mom was difficult, but I'm older and in a different place now -- married to Jeremy and excited for our family to grow. Ali and Aleeah can't wait to meet their new brother or sister. We feel incredibly blessed and look forward to this next chapter in our lives."

The third season of Teen Mom 2 is set to premiere November 12 on MTV ... talk about good timing!

Rawr!

Teen Mom 2 star Jenelle Evans posted photos of her latest ink on Twitter last night, and it looks like she spent quite a bit of time in the tattoo chair for this one!

The 20-year-old reality TV star tweeted, "Haha so cute god I love my new tattoo!!" and there's still no explanation as to why she chose to get a leopard spanning across her hip/butt/thigh area, but she did add, "no no no I got this tiger." Sigh. Doesn't she know that tigers have stripes, not spots?

Check out the gallery below for more photos of Jenelle's massive new tattoo!

Teen Mom 2 star Kailyn Lowry is the proud owner of an enormous back tattoo with pink flowers, mountains, a tree and the phrase, "To the world you are one person but to one person you are the world."

The reality star, who is the mom to 2-year-old son Isaac, has also starred in MTV's show 16 & Pregnant.

Did she think before she ink'd? Let's hope so.

Teen Mom 2 star Jenelle Evans and her fiance Gary Head are both in jail, according to various online reports.

The TV star was reportedly arrested for drug possession while Head was taken into custody for domestic violence.

Evans, who is the mom to 2-year-old son Jace, Tweeted that she did "call the cops." However, the star "told them I didn't want to press charges to jeopardize his career."

The twosome have been off and on for the past few years. On May 16, Head proposed to Evans.

Much maligned Teen Mom star Amber Portwood has been sentenced to five years in prison after failing to complete her drug rehab program.

According to multiple reports, a judge reimposed her five year sentence on Tuesday when the 22-year-old reality star decided to opt for prison after having quit after three months into her rehab assignment.

Portwood was sentenced to three years in prison for possessing prescription drugs without a prescription and an additional two years for violating probation. Instead of her sentence, she struck a plea agreement which allowed her to skip jail upon completion.

Portwood can still avoid serving the entire five years of her sentence depending on "good behavior," where she can reduce her time by up to four years, or one-third of a prisoner's sentence, according to Indiana's prison policy.

There has been no word on when her sentence will begin. Her 3-year-old daughter Leah is in the custody of Gary Shirley, the father.

That's one way to respond to your haters!

Teen Mom star Jenelle Evans got breast implant surgery last month, and now she's showing off the sexy results in a new twitpic. That's one way to spend your MTV money!

Critics slammed the 20-year-old after she was photographed post-op on a beach, looking a little larger than normal. Rumors swirled that she was pregnant again with on-again love Gary Head's baby, but the North Carolina native gave the straight story on the micro-blogging site.

"No I'm not pregnant. No, I'm not fat. Check out my bathing suit. I love it. So bright!" she captioned her bikini snapshot.

The troubled teen star has publicly struggled with balancing parenting duties, which is why she's taking precautions to make sure another little one isn't on the way. "I have birth control in my arm -- it's called Implanon," she wrote.

We guess she's not looking to star on the show's upcoming season!

Jenelle Evans is an even bigger reality star now ... thanks to her recent boob job!

The 20-year-old Teen Mom 2 star, mother to 2-year-old son Jace, posted the above photo and the following, "Now I'm at home recovering with [my best friend] Allison Elise as my nurse." She also added that her implants are the "perfect size."

Evans, who split from Gary Head last month, is now dating Kieffer Delp. She sent a message to Delp directly saying, "Thank you so much for being there for me today and everyday. You are always there when I need the most!"

Aww ... they sound like breast friends.
