The second time mum-to-be shared a picture to Instagram on Saturday (7 June) showing herself and little Jace enjoying a day by the beach.
"Some fun in the sun today with my little man," she wrote by the picture.
After rising to public prominence in Teen Mom, it's no surprise that Jenelle attracts attention wherever she goes. However, she's asked fans to respect the time she gets to spend with son Jace.
Tweeting after her day out with Jace, she said: "It's sad we have to leave his mums resort becuz everyone is following me everywhere I go... Come up SAY HI then please leave me alone. I understand u guys get excited and I'm glad to meet all of u but I also love the time I get with my son and want to cherish every moment."
Jenelle is expecting her second child with boyfriend Nathan Griffith very soon. They celebrated their first anniversary earlier this month, with lucky Jenelle being spoiled by Nathan. His gifts to her included a gorgeous Michael Kors dress, a charm bracelet and a very sweet framed picture of the place they first met.
Jenelle and Nathan have already revealed their baby will be a boy named Kaiser. They threw a baby shower last week, celebrating with friends and family including little Jace.
