Newt Gingrich's love for ABBA and McDonald's

With the return of "Crossfire" to CNN, we are taking a closer look into the hosts' lives with a series of Web videos.

In this peek into host Newt Gingrich’s life outside of politics, the former House speaker and 2012 presidential candidate reveals his unusual phone ringtone and his fondness for a certain fast food establishment.

Gingrich’s ringtone choice, ABBA’s “Dancing Queen,” comes from his appreciation of the musical movie “Mamma Mia,” which he says is “an amazing achievement” and “as energetic and compelling as any scene I’ve seen in a musical, so I really get a kick out of it.”

Gingrich, noted for his love of the latest technologies, also divulged that his wife has a McDonald’s app on her phone, allowing them to locate the nearest restaurant anywhere in the world. Gingrich says he is a particular fan of the Chicken McWrap, noting it is “fairly low cal.” In the next breath, when asked his favorite food, Gingrich doesn’t miss a beat: “A McDonald’s ice cream cone.”

"Crossfire" airs on CNN weekdays at 6:30pm ET.
