Adele's $340 MILLION PRENUP DRAMA!

Figuring out finances put a snag in Adele's wedding plans with sports agent Rich Paul...

- 

It was huge news for Adele fans who'd missed the singer's Las Vegas show or simply wanted to see it for the second, third or seventh time. On March 15, just days before her residency at the Colosseum at Caesars Palace was slated to close, local newscasters reported the 34-year-old planned to extend her Sin City run with dates in the fall and, perhaps, even the summer.

Seeing as Adele was paid an estimated $240 million up-front for her five-month gig, the extension could be very lucrative. While that's great, it adds more fuel to the fire - or cash to the pile - when it comes to her prenuptial agreement with fiancé Rich Paul. "It's a touchy subject: Adele has a few trust issues, which is normal for her, but bringing up a marital contract caused some friction between them," says an insider. "She believes in love, and she says talking about anything to do with money is a sure-fire romance killer. She was right. They've argued about it and that only raised more red flags."
