The couple only announced their split after four years of marriage on Monday (20.07.15) and just hours later their union was officially dissolved in Oklahoma, according to TMZ.

Blake reportedly filed for divorce two weeks ago but the country music superstars - who had a prenuptial agreement - had come to an amicable agreement on how to split their assets.

A statement from the pair said: "This is not the future we envisioned and it is with heavy heart that we move forward separately. We are real people, with real lives, with real family, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."

While Blake was hit with cheating allegations throughout the marriage, a source insisted to PEOPLE that he had been a faithful husband.

The insider said: "Blake is just that incredibly loyal and dedicated husband. I can guarantee you he has been faithful to that woman. He hasn't cheated ever."

Meanwhile, the split came as such a surprise that even Miranda's mother did not know about it.

Beverly Lambert told RadarOnline: "I have no idea what you're talking about. They didn't tell me!"

Miranda, 31, and Blake, 39, married in 2011 but have not been seen together publicly since April.
