Jamie Lynn Spears and her fiance Casey Aldridge have blasted rumours of a split - insisting they are still very much a couple and plan to marry one day.

The teen couple - parents of four-month-old baby Maddie - have become the subject of much tabloid speculation in recent months, with reports suggesting they are living apart, after Aldridge cheated on the 17-year-old actress.

But in an interview with Ok! magazine the pair insists the infidelity rumours are false, and maintain a wedding is planned once their baby daughter is old enough to take part in the ceremony.

Spears says, "We both agree we want Maddie to be a little bit older so that we she can be a part of it, so that she won't just be sitting there the whole time.

"We are engaged and we are really happy with where we are right now. There is no rush for anything."

Meanwhile, a representative for the teenage actress has denied reports Jamie Lynn is already pregnant with her second child.

The publicist states, "She is not pregnant."
