Singers Blake Shelton and Gwen Stefani reportedly cannot help getting affectionate with each other when camera is not around.
According to a source, the couple always makes out when there's no camera spotting them, reports hollywoodlife.com.
"The guy is an old school gentleman and makes sure Gwen knows he thinks she's the most beautiful woman on the planet," the source said.
"He lavishes her with compliments, gifts, and affection - even in public. As long as they know no cameras are on them, they are making out like teenagers," the source added.
