And then there was one.

The championship round heated up between John Rich and Marlee Matlin in their battle to create the best retro 7UP campaign and take home Donald Trump's Celebrity Apprentice crown.

So who was the last competitor standing?

John Rich, that's who. The musician won the $250,000 prize for his charity, St. Jude Children's Research Hospital. The country music star defeated Marlee simply by having the slightly better campaign in the eyes of Trump and the bubbly brand's execs.

"Today has been an unbelievable day!" Rich said. "I got Trump to put on a Stetson hat on national television and now I get to drive down to Memphis with a $250,000 check for St. Jude Children's Hospital. This entire experience has been for the kids and I'm so excited to raise money for this cause and help save lives."
