Levi Johnston Responds to Baby Tripp in the Bristol Palin PSA

Bristol Palin has a new Public Service Announcement for May's National Teen Pregnancy Month featuring her baby son, Tripp, in which the daughter of Sarah Palin talks about the hardships of being a single parent without financial opportunities. Now, Levi Johnston responds to the ad – and the use of his son to make a statement.

"Every time I tried to put him on TV she'd flip out -- but it is nice to see him on there; he's happy and he's looking good," Levi tells our own Samantha Harris. "[Bristol is] sending out a good message."

Levi says that he's been able to see a lot more of his infant son lately and that his relationship with Bristol has improved.
