On Wednesday, the reality star gave out a phone number on his Twitter account, which went to a pre-recorded message saying, "If you buy 100 [downloads of Heidi's music], then I will deliver 100 pizzas to your house – hand delivered! Heidi will come. We'll watch a DVD!"
And on Thursday, an AccessHollywood.com staff member got busy downloading 100 copies of Heidi's song "Overdosin'" on iTunes.
"I am a fan of the Hawaiian pizza, and Heidi and Spencer were recently on beaches of Mexico… I want them to bring me a pizza that tastes like the tropical beaches," the AccessHollywood.com staffer said.
Another staffer hoped Spencer's promise would end up going to a good cause.
"I hope that Spencer and Heidi donate the pizzas to a good cause, like a homeless shelter," she noted.
With 100 people at the Access Hollywood offices now in the midst of enjoying Heidi's music – we're waiting for Spencer to show up with his 100 promised pizza pies!
