NBC “Voice” stars Blake Shelton and Gwen Stefani just started to date, but Shelton's ex-wife, country singer Miranda Lambert, doesn’t believe their romance is new, Hollywood Life wrote in an exclusive report Thursday. She reportedly wants to meet with Stefani’s ex-husband, Bush singer Gavin Rossdale, to discuss her suspicions.

Rossdale, 50, is accused of having an affair with his children’s nanny, Mindy Mann, but Lambert wants to find out if there’s more to the story. She too was accused of being a cheater. “[Lambert] feels like both she and Gavin are being made out to be the cheaters to benefit their exes. She just thinks it’s strange that now all of a sudden the nanny scandal news broke instead of months ago when it apparently happened,” the source told Hollywood Life.

One of the main things she doesn’t believe is Shelton and Stefani’s romance recently blossomed. “She doesn’t buy their story that it’s totally brand new. She thinks they’re just trying to cover it up so they don’t look bad,” the insider said. “Miranda believes something’s been going on between these two for a lot longer than they’re letting on.”

Shelton, 39, and Lambert, 32, divorced after the Fourth of July. They said a split wasn’t what they had “envisioned as a couple” and asked for their privacy.

A month later, Stefani, 46, and Rossdale, 50, announced they would breakup. Their divorce was finalized last month.

Even though Rossdale has been bombarded with cheating accusations, he has not responded to the rumors. He is reportedly focusing his attention on the three children he shares with Stefani: Kingston, 9, Zuma, 7, and Apollo,

The No Doubt singer alluded to the infidelity during an interview with KIIS-FM, Los Angeles, Monday. "Everybody knows that my life blew up last February. I'd just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life, and it's not. I don't know what happened," she said.
