At first Leah and Jeremy's marriage was a secret of course due to their contract with MTV, however since the cat is out of the bag on that one, Leah finally changed her name on twitter to Leah D. Calvert. Confirming that she has in fact taken his last name.
Hopefully this will be the last time she gets married! I'm sure it will thought because even just through pictures and tweets I can tell their relationship is very different from the one Leah had with Corey. While I am a little sad inside that Leah and Corey didn't end up together... since I rooted for Leah and Corey from the moment I saw their 16 & Pregnant episode! I am happy that Leah has found happiness and finally has a little relief from all the stress she has dealt with the past few years.
