Jade Roper and Tanner Tolbert, who got engaged on Bachelor in Paradise 2 last summer and will be appearing on Marriage Boot Camp: Reality Stars this fall, are talking about kids! "We're building a house right now," Tolbert told Us Weekly of their ongoing project in Kansas City, MO. "It's going to be done in the spring, so we'll have to start filling it up after that." Added Roper about starting a family with her husband of eight months, "I've been whispering in Tanner's ear, trying to just feel it out, put it out there." Tolbert, 29, admitted he's actually up for having children soon. "I bet you something, maybe next year," Tolbert said. "Yeah," Roper agreed, "some time next year, we'll start." Tolbert then joked about wanting "two-and-a-half" kids because he's desperate to have a son. "He has a stipulation," Roper, 29, revealed with a laugh. "So if they're both girls," Tolbert explained to the magazine, "I want to try for No. 3, for a little boy." "Yeah, he wants one boy," the brunette beauty chimed in. "So, I'm hoping the first one's a boy." "Get it out of the way!" Tolbert interjected. "And after that, the pressure's off," Roper confessed. Roper and Tolbert are the only couple still married from the first three seasons of Bachelor in Paradise, however, Season 3 ended with three couples engaged. Marriage Boot Camp: Reality Stars premieres Friday, October 7 at 9PM ET\/PT on WE tv. The Bachelor starring Nick Viall returns to ABC in January 2017.
