Melissa McCarthy is reportedly refusing to attend her cousin Jenny's wedding.

The Tammy star - who is reportedly feuding with the blonde beauty - doesn't want to witness the television host, 41, tie the knot with her fiance Donnie Wahlberg. "The cousins were close at one time, but they've grown distant over the past few years," a source told The National Enquirer.

The cousins fell out after Melissa, 43, allegedly ditched the former Playboy model after her career took off and she sprung into the limelight. "Jenny feels she helped Melissa get a leg up in the business. But now that Melissa's career is skyrocketing, Jenny feels [Melissa] doesn't have time for her," the source explained.

Meanwhile, Jenny recently revealed she and Donnie, who proposed to her in April, will be tying the knot "very soon" and she's now in a rush to find the perfect gown in time for her big day.

However, The View host - who has 12-year-old son Evan from her marriage to John Mallory Asher - has already ruled out a frock that will enhance her bust. "I don't want to be too busty in my wedding dress. I think when brides are too busty it takes away from the beauty of the bride. It will be form fitting, but not too over done," she explained.
