Have Jessica Simpson & Her BFF Ken Paves Had a Falling Out?

Say it isn’t so…Jessica Simpson and Ken Paves may have had a falling out…OMG!!! After all these years, the boyfriends and the drama…the twosome may have split up!

Jessica Simpson’s main- and mane- man Ken Paves knows all about, uh, splits and ends, but we never thought these two would part.

However, according to a source close to the singer, the hitherto constant companions are “over.” The suddenly former BFFs, almost inseparable over the years, had some problems over the summer, with Paves no longer speaking to Simpson over “something petty.”

“They’ve had a major fight,” the Simpson insider tells E! News. “Jessica’s devastated over it, she loves Ken. He just won’t speak to her at all.”

Simpson tried to make amends, even inviting Paves along to her 30th birthday party in Capri in July, where she brought along her family, girlfriends and new boyfriend Eric Johnson for a relaxing getaway.

Paves, who was always Jessica’s shoulder to cry on though her many loves and losses, turned her down.

“She was so upset,” says the source.

Along with some other drama, Jessica is said to be upset that Ken has been tweeting his love for his other galpal, Eva Longoria, calling her his “best friend.”

“Jessica was heartbroken, they were so close. Maybe one of them will come around,” the source says.
