Jenelle Evans Post-Baby Body: 'Teen Mom 2' Star Hits The Beach After Birth Of Second Son

Jenelle Evans is back to her normal routine.

Just one week after giving birth to her second son, Kaiser Griffith, the Teen Mom 2 star was back on the beaches of South Carolina -- and sharing personal photos of the outing with fans.

"You would expect her to be enjoying some much deserved relaxation time at home after giving birth to her son Kaiser less than a week ago, but that seemed the last thing on Teen Mom's Jenelle Evans' mind as she flaunted her figure in a bikini in a Twitter snap," the UK's Daily Mail reported on July 7.

On Monday, June 30, Evans and her boyfriend, Nathan Griffith, welcomed their first child together. The pair, who began dating one year ago, also have children from previous relationships. Evans has a four-year-old son, Jace, with her former boyfriend, Andrew Lewis, who fans have seen on Teen Mom 2, and Griffith has a two-year-old daughter, Emery, with his ex-wife, Allison Stevens.

In the photo posted to Twitter, Evans was seen lying on her back in a bikini with her eyes closed. In the caption for the photos, she wrote, "#Relaxation," along with a beach emoticon.

In just a couple of weeks, Evans and Griffith will be returning to MTV in the second half of Teen Mom 2 season five, which follows the couple as they prepare for the birth of their son, Kaiser, and deal with the possible consequences for Griffith's Sept. 2013 DUI charge.

Teen Mom 2 returns on July 16 at 10 p.m. on MTV.
