Student Casey Aldrige insists reports he cheated on teen actress Jamie Lynn Spears while she was pregnant with the pair's child are bogus.

The teen couple welcomed baby Maddie into the world in June - and are now planning to wed, according to reports.

But their relationship was rocked this week by tabloid claims made by Aldridge's ex Kelli Dawson.

She tells the current issue of In Touch magazine that she enjoyed a long-term affair with the 19-year-old hunk - while his girlfriend, Spears, was six months pregnant with his first child.

But Aldridge has denied the allegations, accusing his 28-year-old ex of fabricating the story to make money.
