Robert Pattinson, who rose to fame as Edward Cullen of the Twilight franchise, has reportedly run into financial trouble.

And according to a report on Radar Online, Pattinson's girlfriend, FKA twigs is the reason behind his funds running out.

A source told the website: "He has always lived large and spends money like there is no end, but the truth of the matter is that his fortune is shrinking because he is no longer a franchise star."

Previously, OK! magazine reported that Pattinson was running low on funds because "his spending habits are the same as when he was earning big bucks, so there's a real shortfall."

However, a source told Radar Online, "Rob is not working right now because he is so focused on her. He insists on paying for everything because that is the kind of guy that Rob is."

According to the insider, "FKA is not a dumb girl and she knows how to work men and has even been called a gold-digger by people who know her."

"Although they both spoil each other, but she has pennies compared to the kind of money he has."

Another report claims that the whole news is not true. A source close to the actor told Gossip Cop, the allegation that he is struggling with money is a "total lie".

The website states that if Pattinson was so concerned about his cash flow and twigs' motives, he would simply stop spending money and stop dating her.

The website also debunked the claim that Pattinson was not working "because he is so focused" on the singer.

The Twilight star's new movie, Childhood of a Leader, just started filming in Budapest earlier this week. Pattinson also has another movie, The Lost City of Z, in pre-production stage and two movies - Life and Queen of the Desert, that will start filming soon.
