Heidi reportedly ready to leave Spencer

Heidi Montag and Spencer Pratt have called it quits.

"Heidi is looking to move out due to all the fake bad press that Spencer controls," a rep for the Hills star, 23, tells TMZ.com."She's tired of it and is looking for a place and wants to focus on her acting career."

TMZ says Montag — who has been making the case to replace Megan Fox in “Transformers 3” — is looking for a new home in Malibu, Calif.

A source tells the Web site tension has been growing between the couple, who wed in April 2009: "It wasn't just a sudden thing."

On Tuesday, Montag Twittered, "I am not Heidi Pratt, I am Heidi Montag."

Us Weekly has reported she was influenced by Spencer, 26, to undergo 10 plastic surgery procedures in one day. Spencer has also bragged that he doesn't allow Heidi to watch television or go online.

"He's brainwashed her!" a source told Us Weekly. "He's made her turn her back on her family."

"All guys are a little bit controlling," she said.

Their behavior had grown increasingly erratic. Pratt hired four ex Marines to guard their L.A.-area home, and they blew over $400,000 on healing crystals. Heidi even called the police when her mom Darlene Egelhoff showed up unexpectedly at their house earlier this month.

Heidi Twittered that she'd be wed to Spencer "FOREVER!!!" after they walked down the aisle in April. (They also eloped in November 2009.)

Said Egelhoff then, "He's literally what she's dreamed of her entire life. She always wanted to get married young, and she just prayed and prayed for someone exactly like him."
