with a 28-year-old woman while Jamie Lynn was expecting the couple's first
child.
The 'Zoey 101' star - who gave birth to daughter Maddie Briann in June - is
said to have been oblivious that her 19-year-old husband-to-be was cheating
on her with Kelli Dawson.
Kelli said: "He totally instigated it and pursued me."
However, Casey slowed things down with Kelli as Jamie Lynn neared the end of
her third trimester, because he was so overcome with guilt.
Kelli added to In Touch Weekly magazine: "Casey had to deal with the baby
coming, and it had to stop. But even after we stopped having sex, we would
still kiss occasionally.
"I still see him all the time, at least once a week."
The pair's relationship has also been confirmed by Jason Alexander, who was
famously married to Jamie Lynn's older sister Britney for 55 hours after a
Las Vegas wedding in 2004.
Jason said: "Kelli and Casey have been a couple on and off for a few years.
They were a really tight couple, but I think it was hard for Kelli, having
Jamie Lynn in the picture."
