Will Blake Shelton pop the question to Gwen Stefani during a taping of "The Voice"? Rumor has it, the couple, who found love on the TV singing competition, receives "an exceptional bonus to keep the spark alive on-camera."

"[Blake and Gwen] are getting paid an exceptional bonus that is significantly higher than the other judges to keep the spark alive on-camera," a source reveals, "They are starting to film the promos next week and have already shot a couple of live spots."

According to the source, "The Voice" execs want Blake to propose to Gwen during filming. "Bosses are really, really pushing for this," explains the source, "They want nothing more than for Blake to propose to Gwen during a taping of the show."

"The producers really want to see Gwen and Blake in competition more often this upcoming season, versus working with each other like they have in the past," the source tells Radar Online, "And, of course, there is a stipulation in their contract, which is more of a break-up clause. If, for some reason, they call it quits, they are both required to finish out the remainder of their existing contracts."
