CAMBRIDGE (CBS) – Harvard University is adding on to its long list of celebrity graduates. HGTV stars Chip and Joanna Gaines are among the celebrities who completed a four-day business course over the weekend.

The couple had some famous classmates, including singer Ciara, the NBA’s Kevin Love and Julius Randle, NCIS: Los Angeles actor Eric Olsen and Australian soccer star Tim Cahill.
