Levi on Baby No. 2: We 'Forgot the Birth Control' Bristol: I don't want Tripp to have '10 half-siblings' By Evann Gastaldo, Newser Staff Posted Apr 13, 2012 9:35 AM CDT 19 comments Comments In this Aug. 8, 2010 file photo, Levi Johnston arrives at the Teen Choice Awards in Universal City, Calif. (AP Photo/Chris Pizzello, File) (Newser) – In case you missed the happy news, Levi Johnston has confirmed he will in fact be a dad for the second time now that girlfriend Sunny Oglesby is pregnant, and yesterday he shared the charming story of his child-to-be's conception with the Insider. "There was a time we went to the cabin and forgot the birth control pills and, you know, about a month later we found out we were having a baby," Johnston explains. The couple also addressed Johnston's relationship with the Palins, with Johnston complaining that he doesn't "feel like a dad" to son Tripp, through no choice of his own. Oglesby adds, "I'm tired of people thinking that my boyfriend's a bad father, especially now that I'm having his baby." Meanwhile, Bristol Palin tells In Touch that when she first heard Johnston was expecting again, "I said, 'No way, shut up!'" She says she thought he "learned his lesson the first time," and adds that she doesn't want Tripp "to go to elementary school with 10 half-siblings."
