Reality star Adrienne Maloof will not return for season four of The Real Housewives of Beverly Hills because she was fired from the show, a source confirmed to People magazine.

The insider close to the Bravo show said Maloof was "let go" and that "producers were sick of her constant tardiness and her issues." However, a source close to the 51-year-old disputed the claims, saying, "It was her decision to leave. Adrienne is very happy."

"Housewives was part of her past. She's looking to the future," the source close to Maloof said.

The reality TV star did not appear in the season three reunion special of Housewives, citing legal reasons related to her divorce from Paul Nassif. News of her departure from the series follows the announcement that Camille Grammer will also not return for season four of the show. She was not a standard cast member in season three but made frequent appearances throught the season. Grammer also did not attend the taping of the season three reunion show, which filmed on March 1.

"Camille has decided not to go to the reunion taping," a source told Radar Online. "She wasn't on the show that much during the past season and feels there really isn't any need for to her to go. Camille has also told producers that she won't be returning for the fourth season.

"She was so thankful for the opportunity to be on the show and made some great friends, but it's just time now for her to move on."
