Rumors are swirling around Antonio Banderas and a beautiful young Dutch banker, Nicole Kempel.

Wife Melanie Griffith filed for divorce from Banderas on June 6, after 18 years of marriage. RadarOnline is reporting that the relationship with the young, Dutch woman may have something to do with the June filing.

According to a source for Radar, Banderas is not only dating and in love with Kempel, but he was already in a relationship with the statuesque beauty prior to the divorce filing in June.

The new couple were allegedly first spotted together in Cannes on May 20, dancing the night away at the De Grisogno Fatale party during the film festival. A few days later, they were again spotted enjoying a romantic boat trip together off the coast of the French resort town.

“He is really in love with her. He comes to France to visit her when he can, and they already went for a ten-day vacation together in secret,” the source told Radar.

The couple — and Griffith — have been trying desperately to keep the relationship on the low-down as Banderas and Griffith hash out the details of their divorce.

“Only her closest family and friends knew,” the source said of Griffith. “They were hiding everything from everybody because Melanie got a very good divorce lawyer, and I think he was hoping to keep it under wraps until the end of the divorce.”

However, Banderas and Kempel couldn’t keep their love secret for long. They were reportedly spotted partying it up together in St. Tropez last month, and later hiking in Ferrat, France, on August 28.

Other sources told Hola! magazine that Kempel was not the reason for his split from Griffith, but admitted that the Spanish actor “is in love with her.”
