Blake Shelton and Gwen Stefani made their first red carpet debut together at the Vanity Fair Oscars party Sunday. “The Voice” coaches walked hand in hand amid rumors that Stefani was breaking up with Shelton.

Stefani looked absolutely stunning in her red gown with tons of sheer fabric and only silk roses covering her chest and hips. Shelton arrived in a semi-casual look wearing dark jeans and black shirt teamed up with black blazer.

During the event, Shelton also supported his girlfriend while she performed “Hollaback Girl” to kick off the party.

The two, who announced their relationship in November last year, have been recently surrounded with several rumors. The latest rumor about the couple was that Stefani wanted to split with Shelton because of the “Sangria” singer’s ex-wife, Miranda Lambert.

OK! Magazine reported that the drama between Shelton and Stefani started after Lambert, 32, discovered that Stefani supposedly called her a “redneck harlot.” Lambert reportedly tracked down Stefani’s cell phone number and called her repeatedly, up to four times a day.

“Gwen didn’t bother picking up because the calls were coming from an unknown number. But at some point, she got annoying and texted back, ‘Who is this, and how did you get my number?’” an insider told OK! Magazine. Lambert reportedly slammed Stefani saying that her career was “over” and her music hadn’t “been relevant since the ’90s.”

Stefani reportedly accused Shelton of leaking her number to Lambert. “He told Gwen to calm down and tried to brush off the situation, explaining that it was just Miranda’s tough ‘country gal’ personality coming through and that Gwen shouldn’t get too worked up about it,” the insider told OK! Magazine.

However, Gossip Cop debunked the report saying that the couple has no plans on ending their relationship.

Over the weekend, Stefani mocked the split rumors by posting a photo of her near the latest edition of OK! Magazine reporting about her breakup.

Stefani was also recently surrounded with rumors that she is pregnant with Shelton’s twin children and was also spotted hiding a baby bump.
