Country star Blake Shelton has laughed off a new tabloid report suggesting Gwen Stefani is pregnant with his first child.

The Honey Bee singer went public with his budding new romance with Stefani last week, when The Voice co-stars were photographed holding hands as they headed to a party following the CMA Awards in Nashville, Tennessee.

Sources tell America's OK! magazine their relationship has become really serious and now Stefani is expecting his baby - but Shelton has made it clear the rumours are false.

"To quote my friend @BradPaisley 'The more they run my name down the more my price goes up...,"' he wrote on Twitter.

He went on to brand the unfounded rumours "bulls**t", and after one fan joked about also carrying his "love child", he quipped, "Damn I'm fertile!"

Ha!!! You too!!! Damn I'm fertile!! https://t.co/VKRedSlyOv

Shelton's Twitter denial emerges a week after a representative for Stefani appeared to confirm reports the couple was dating in a statement, which read: "Gwen and Blake are longtime friends who have very recently started dating."

However, the No Doubt singer, who announced her split from husband Gavin Rossdale in August, recently insisted the "official" line didn't come from her.

"I never said nothing about being in a new relationship," she told America's syndicated Frankie and Geena Morning Show.

"I don't know who said that but somebody did.""My kid came in last night to tell me about it," the mother-of-three continued as she remained coy about her relationship status with Shelton.

"So, that's how crazy my life is. People can just say whatever they want and then they can just believe it."

Stefani previously dodged questions about her dating life in another radio chat with Los Angeles DJ Ryan Seacrest, but she didn't attempt to hide her feelings about Shelton, revealing, "I do think he's hot, don't you?"

The reported new romance is Shelton's first since he shocked fans in July when he announced he and fellow country singer Miranda Lambert had quietly divorced after four years of marriage.
