"Teen Mom 2" star Jenelle Evans is probably busy planning her wedding to Nathan Griffith. The 22-year-old MTV star is engaged to her boyfriend of two years and shared the exciting news with her fans on Instagram.

"Oh man! Someone's engaged," Evans wrote on Jan. 6, posting a picture of her massive diamond ring.

"Gorgeous," she captioned another photo of her new bling.

On Twitter, Evans revealed that her ring is made of Tolkowsky diamonds and they "aren't cheap." The couple welcomed their first child together, a baby boy named Kaiser, on June 30.

"I'm so blessed to have my little family," she tweeted at the time.

This is the second child for both Evans and Griffith. The MTV star is mom to 5-year-old Jace with ex-boyfriend Andrew Lewis, and Griffith has a 3-year-old daughter named Emery from a previous relationship.  

Shortly before Evans gave birth to her second child, she dished to US Weekly about how she came up with the name Kaiser.

"We were basically searching for baby names on the internet, and we came up with a bunch of different unique ones. We didn't want something that everyone else had or had even heard before," she said. "So we wanted something different, and we ended up looking up Kaiser."

Evans rose to fame on MTV's "16 & Pregnant," which chronicled her first pregnancy with Jace. She went on to star on the spinoff show "Teen Mom 2" and is currently filming for its sixth season.
