[cnn-photo-caption image= http://i2.cdn.turner.com/cnn/2008/images/12/30/art.palin30.gi.jpg caption="Bristol Palin with Levi Johnston, mother Sarah Palin and brother Trig at the GOP convention."] Alaska Governor Sarah Palin hasn't yet said anything publicly about her 4-day-old grandson, Tripp, but she does want people to know that Tripp's parents – her eldest daughter Bristol and her fiancé Levi Johnston – are hard at work and keeping up with school.
"You need to know that both Levi and Bristol are working their butts off to parent and going to school and working at the same time," Palin told PEOPLE in a phone message Wednesday. "They are certainly not high school dropouts."
The former vice presidential candidate said she wanted to be clear about their continuing work toward high school degrees because any suggestion otherwise "harms Bristol's reputation and Levi's reputation and their chances for good work opportunities."
