We're guessing most people don't realize it, but Melissa McCarthy and Jenny McCarthy are first cousins.
They don't look much alike, and they don't spend much time together as a result of a falling out several years ago.
Jenny and Melissa have been cordial when speaking about one another in the press, so it was widely assumed that they'd patched things up, but simply hadn't grown close again.
According to a recent report, however, the bad blood between these two is worse than ever, and Jenny has fired the latest shot in their ongoing feud by refusing to invite Melissa to her wedding!
Yes, Jenny is marrying Donnie Wahlberg soon (they're keeping the date a secret), and despite friends and family urging her otherwise, she's sending a message to her cousin by not sending her an invitation.
The ill will dates back to 1997 when Jenny gave a struggling Melissa a part in a sketch on her talk show. Jenny later advised Melissa that she'd have an easier time making it as an actress if she lost some weight.
Melissa took the comment to heart, and reportedly bad mouthed her cousin in a way that Jenny has never been able to forgive.
Melissa recently confirmed to Howard Stern that she won't be attending Jenny's wedding.
