Pregnancy rumors surrounding Gwen Stefani resurfaced Wednesday after OK! Magazine reported that the singer is having twins with Blake Shelton. Recently, Stefani has been gushing over her romance with Shelton just as the latter's ex-wife Miranda Lambert released her first single since her divorce.

“The buzz in their inner circle is that Gwen is four months pregnant, and that they’re expecting twins," a source told the magazine. The couple “began researching fertility doctors and evaluating their options several months ago.” The source added that Stefani “conceived naturally.”

The report also said that Shelton and Stefani got married secretly in a close ceremony that was "a small, casual affair."

However, Gossip Cop debunked the report, saying that there was no truth to it.

Meanwhile, a report by Star Magazine said that a wedding for Stefani and Shelton may be around the corner as they are looking into prenup planning, according to Hollywood Life.

Over the last few months, several rumors surfaced that Shelton and Stefani will get married soon and that the couple is expecting a child.

OK! Magazine reported in May that the "Make Me Like You" singer is “due on her 47th birthday,” in October and is having a baby girl. However, this report was also rejected by Gossip Cop.

Stefani and Shelton first addressed dating rumors last November, just months after they split up from their respective spouses.

On Monday, Shelton's ex-wife released her new song "Vice," in which she speaks about "heartbreak" and being "numb" and "lonely."

Lambert and Shelton dated for six years before getting married. The two announced their divorce last July. While the reason for the split was unknown, the two were surrounded by several cheating rumors. Most recently, infidelity allegations resurfaced with OK! Magazine reporting that Lambert owned up to her friends that she was the real reason behind the breakup.
