Nadine CoyleNadine CoyleThe course of true love never did run smoothly.

And we reckon Nadine Coyle will vouch for that...

She's had a hard ol' slog with her on-off man, Jesse Metcalfe.

So what's the romantical dealio with them at the mo?

Well, apparently it's all back on.

Nadine binned Jesse back in April after whisperings that he had cheated on - which he strongly denied.

But according to reports Jesse has finally re-wooed his fair maiden.

And to prove his love he forked out thousands of pounds for Nadine to fly to India on an all-expenses-paid holiday in Mumbai, where he's filming his latest movie.

Nice... well, it would have been if they hadn't forgotten one minor detail - her visa.

A source told the Daily Mirror: "She was in floods of tears - she was desperate to join Jesse and spend some quality time with him.

"Jesse and Nadine are back on and their relationship is stronger than ever. They have been through a lot this year, but it's all behind them and they're ready to tell that world they're a couple again."

Fortunately, you don't need a visa for that.
