Kailyn Lowry, 28, appears to still be pregnant. The Teen Mom 2 star hinted that she’s still carrying her baby bump after hopping onto Instagram on July 28, where she came across a photo of her ex-husband, Javi Marroquin, hanging out with their son Isaac, 10, and her other son Lux, 2 (whom she shares with ex Chris Lopez) at a water park amid a vacation without Kailyn. The picture, posted by Instagram fan account @teenmomshaderoom_, prompted one theory from a fan.
