Remember how we thought Ashton didn't invite his own brother to his wedding? Turns out he was invited. The Scoop reports:

Why wasn’t Ashton Kutcher’s twin brother there when the star married Demi Moore?

His mother says it’s because Ashton’s sister-in-law has a big mouth.

“We were determined to keep the wedding a secret and we though the best way to do that was keep Melissa [the wife of Ashton’s brother, Michael] out of the loop,� Diane Kutcher tells the forthcoming issue of Star magazine.

Melissa and Michael are splitting, and some in the family claim that the soon-to-be ex-wife has loose lips.

“Michael was invited,� Diane Kutcher told the mag, but he didn’t attend because he was reportedly worried that Melissa would learn of his travel plans and Demi and Ashton’s secret wedding would no longer be a secret. The absence was, says the mother, “a favor to Ashton from a loving brother.�

Gosh and Melissa was so bitchy and vocal about not being invited - no wonder Michael is getting a divorce.
