Jenny McCarthy is getting ready to marry New Kids on the Block heartthrob Donnie Wahlberg, but sources say her cousin Melissa McCartney is banned from the wedding ceremony.

The two stars used to be close, but they grew apart after Jenny told the up-and-coming actress she would never make it if she didn't lose weight.

Melissa obviously proved her wrong.

Jenny still thinks Melissa owes her a lot for her success but she hasn't heard a thank you from her cousin yet.
