and Levi Johnston
are, in fact, shopping around the idea of a reality show about their relationship
-- but the sticking point appears to be the level of commitment on the network side.
"They want a commitment for an entire series, but right now, there's only been interest in testing this out as a pilot," an industry source close to the situation tells PEOPLE, adding that negotiations are ongoing. "There aren't a lot of options for them out there, and this is their best chance at making a decent amount of money."
Palin, 19, and Johnston, 20 -- parents of an 18-month-old son, Tripp -- recently reconciled
and are reportedly planning to marry
after breaking off a previous engagement in March 2009. Johnston has also apologized
to Bristol's mother, GOP star Sarah Palin
, for negative remarks he made about the Palin family after the breakup.
Sarah, 46, has yet to publicly give her blessing
to the couple's reunion. But one person who hopes that will happen is comedian Kathy Griffin
-- who famously befriended Johnston when they met at last year's Teen Choice Awards, and visited him in Wasilla, Alaska, on her show, My Life on the D-List
"I wish the best for them," Griffin, 49, told PEOPLE at VH1's Do Something Awards on Monday. "I've spent a lot of time with Levi. I don't think he ever fell out of love with Bristol, and he's expressed that many times. So, I hope that Sarah Palin does make peace with the situation, because he is the baby's dad."
Should Bristol and Levi get their reality show, and get back in Sarah's good graces, she might be able to offer some tips: Palin's own reality show, for TLC, has already started filming. --Tim Nudd
