Blake Shelton and Miranda Lambert are using humor to shoot down rumors that their relationship is in jeopardy. 

In a Twitter exchange, Shelton told her that he'd "just read in a tabloid" that their "marriage is falling apart!!!"  Lambert replied, "Oh no! Can't wait to read if we make it or not."  Blake then retweeted her response, adding that he's "making her funnier." 

The rumors were sparked by a tabloid headline claiming that Shelton was having an affair. 

Shelton and Lambert will celebrate their second wedding anniversary in May.  They'd been a couple for five years prior to their marriage.
