Casey Anthony was once known as “America’s most hated woman.”

No wonder. As cops hunted for her missing toddler, Caylee, Anthony earned the moniker of America’s most notorious party girl.

The tabloid curiosity has rarely been out of the headlines since she was acquitted in 2011 of murdering her two-year-old daughter.

Now, the New York Post reports that Anthony, 38, has kicked her aerospace engineer paramour to the curb. Sources told the Post that Tyson Ray Rhodes left his wife in January for the Florida woman.

“She gets bored easily,” a friend told the tabloid. “It was very exciting when he was married because he was the forbidden fruit.

“But once she had him, there was nowhere to go.”

The pal added: “What was she going to do with him? She grew tired and restless, so it was time to move on.”

Anthony and Rhodes first hooked up in January and as recently as September were spotted in a Florida watering hole together. Spy-witnesses said the duo were “holding hands and kissing.”

The pair reportedly met at a gym where they were both members. Sparks flew when they joined a gym rat group chat.

According to the Post, the clandestine couple began direct messaging each other. And when he moved his family to Tennessee, Anthony coupled her wagon to the married man and rented an apartment near his home.

The duo were spotted in September moving things from her Murfreesboro apartment in his pick-up truck. They then headed to the house Rhodes shared with his wife of 22 years.

However, a source close to Rhodes family claims the love rat now believes he made a huge mistake by ditching his wife for the party girl.

“He regrets leaving his marriage for her,” a source close to the family said of the father-of-two. “He wasn’t thinking clearly. He has a lot of repairs to make. I wouldn’t want to be him right now.”

His wife, Sandy, was apparently “blindsided” by the affair.

Casey Anthony exploded into the national consciousness in 2008 when her two-year-old daughter disappeared. Caylee had been missing a month before Anthony’s mom filed a missing persons report.

During the drama, Anthony was captured partying at nightclubs and raunchy house parties.

The little girl’s remains were discovered wrapped in a blanket near Anthony’s home. Her mom was arrested and charged with first-degree murder with cops claiming she killed the child so she could party.

She was later acquitted but she never strayed far from the headlines. She told one documentary that she wasn’t partying when her daughter disappeared, she was actually working.

Anthony was photographed participating in a “hot body” contest at the time of the disappearance. She also blamed her father, who has denied any wrongdoing.

She added that she believed Caylee was alive — and that her father was holding the child captive.

Anthony’s father was never arrested in connection with Caylee’s disappearance and subsequent murder.

He testified for the state of Florida during her trial, telling a jury how he smelled the odour of a dead body in Casey’s car weeks after Caylee vanished.
