Miranda Lambert has reportedly slept around the entire course of her marriage with Blake Shelton, a source closed to the couple revealed. To make matters worse, Lambert is said to have slept with Shelton's best friend and four other men while still married.

Lambert is rumored to have cheated with Shelton's best friend Jamey Johnson in 2007. However, it is Major League baseball player Josh Beckett whom she had fallen head over heels with.

At the time of cheating, Beckett is said to be dating a childhood sweetheart whom he eventually married. Beckett and Lambert, however, stayed in love with each other.

"Josh was dating his childhood sweetheart Holly when he first got involved with Miranda, Holly may have known about the affair but she married him anyway," the source was quoted as saying by Celeb Dirty Laundry, citing this week's edition of Star Magazine.

The two have maintained constant communication, the source said. The affair, in fact, had gotten to a point where Beckett asked for Lambert to leave Shelton.

"Even when his new wife got pregnant, Josh still pined for Miranda and pressured her to dump Blake for him. The truth is Josh was Miranda's other real love," the source said.

In a related report from the Hollywood Life, the source said that Lambert had gotten to a point where she has decided to leave Shelton for Beckett. However, her management advised her otherwise.

"He [Josh] did not want to be her side piece. She wanted to leave Blake for him. But her management urged her not to," the source said.

When her affair with Beckett went down the drain, Lambert is said to have started an affair with Chris Brown. But since this, too, has no way to go, Lambert moved on. At one point, she then slept with two of her employees on tour.

Shelton started feeling something was amiss when Lambert started acting crazy. She was playing reverse psychology on him, accusing him of infidelity. Shelton then decided to hire a private investigator to find out the truth behind Lambert's unfounded accusations.  

"Blake flew to one of her shows to confront them and he caught her hugging the other man. They were forced to admit everything, it was obvious what was going on," the source said.

Shelton recently decided to end his marriage with Lambert. He filed for divorce, wanting so much to get out of their marriage. He was reportedly furious that he could no longer spend another day with Lambert.
