MTV reality star Jenelle Evans welcomed her first son with boyfriend Nathan Griffith and her second overall on Monday. Baby Kaiser joins the "Teen Mom 2" star's first son, Jace, who was born while Evans starred on MTV's "16 and Pregnant" almost five years ago. Griffith shared a photo of her newborn son's feet via Twitter on Monday, slamming rumors that the pair was at the beach. After revealing the news about their pregnancy in February, Evans told Us Weekly that she and Griffith had been looking for baby names on the Internet for a while. "We came up with a bunch of different unique ones," she said at the time. "We didn't want something that everyone else had or had even heard before, even us. So we wanted something different, and we ended up looking up Kaiser." Evans, 22, is currently working toward a surgical assistant degree at a tech school.
