Jenelle Evans shares bikini photos from St. Thomas

ST. THOMAS, Virgin Islands, Jan. 14 (UPI) -- Jenelle Evans and fiancé Nathan Griffith enjoyed time in St. Thomas last week.

The 23-year-old reality star posted a series of photos from the vacation on Instagram. Evans appears in a bikini in several of the pictures, just over six months after giving birth to her second son, Kaiser.

Evans and Griffith were in the tropical locale for a week, and got engaged Jan. 6. The couple have been together since April 2013, and welcomed Kaiser in June 2014.

Evans came to fame on season two of MTV reality series 16 and Pregnant, and subsequently appeared on five seasons of Teen Mom 2. The reality star is also mother to 5-year-old son Jace with ex-boyfriend Andrew Lewis, and will return for a sixth season in 2016.
