Fergie's mom, Terri Jackson, spilled the beans to Ryan Seacrest about her daughter's weekend nuptials in Malibu, California. The Black Eyed Pea and her new hubby, "Transformers" star Josh Duhamel, held a star-studded reception on Saturday, where everyone from Kid Rock to Will.I.Am made an appearance.

"It was such a blast — 350, 375 people were there and that was keeping [the number of invitees] way down," she revealed to the "American Idol" host on his radio show Monday morning (January 12). "So many people couldn't bring a date unless they paid me money or something! It had to be someone you're actually engaged to or something like that."

She added, "[It was so much fun] you can hear it in my voice!" Jackson also said that there are probably a slew of other hoarse people out there after they performed for the newly married couple.

"Kid Rock was there, with Will.I.Am rapping," she said. "It was an amazing show. It would cost you a fortune — and I'm sure it did — to see this show."

There was also an unexpected performer that managed to secure a spot on the stage. ["Fresh Prince of Bel-Air" star Alfonso Ribeiro] was amazing," Jackson said. "That guy can sing! Fergie and he have been friends for years."

"I've never seen either of them look more beautiful," she said about the couple. Describing her daughter as "amazing," she also joked around about the rumors that Fergie and Duhamel are expecting a little bundle of joy. "Yeah, that's it [she's pregnant]! Josh's mother [is like], 'Would she hurry up and have that elephant?' "
