In addition to her appearance on next Tuesday’s Oprah, Octomom Nadya Suleman will pop up for a guest spot in a skit that will air during Idol Gives Back, American Idol’s annual charity fundraiser, premiering next Wed., April 21 on FOX.

On Wednesday, President and First Lady Obama filmed a taped message that will appear as part of American Idol’s annual global fundraising event later this month, FOX News reports.

Idol Gives Back is a two-hour charity event that raises money for international non-profit organizations. This year’s beneficiaries include Children’s Health Fund, Feeding America, Malaria No More, Save the Children, and the United Nations Foundation.

Idol Gives Back 2010 will air Wednesday, April 21 @ 8 PM ET.

Conan O’Brien has been invited to participate in FOX’s annual Idol Gives Back special on April 21, but there’s a contractual provision in his departure agreement with NBC that might prevent that. Sources close to the discussions say Coco’s current contract with The Peacock prohibits him from making any TV appearances until May 1.
