'Teen Mom:' No, I'm not pregnant again

'Teen Mom:' No, I'm not pregnant againCatelynn Lowell, of MTV's "Teen Mom," Wednesday denied a report that she and fiance Tyler Baltierra are expecting their second child. "Don't believe everything you read; I'm definitely not pregnant!" she told Us Weekly in a statement, countering a claim on the cover of the new issue of In Touch magazine. "I'm on the pill. And, I'm only 20 -- I don't want to have kids until I'm out of school and we're married." Lowell and Baltierra, 19, had a daughter, Carly, that the couple placed for adoption three years ago, Us said. The two have set a July 15, 2013, wedding date.
