Brunette bombshell Megan Fox proved who really wears the pants in her household when she manipulated longtime boyfriend Brian Austin Green into getting rid of his beloved pooch so that she could adopt a pair of tiny tailwaggers of her own.

The 21-year-old vixen gave Macy the boot after claiming the 3-year-old mastiff pit bull mix gave her the willies.

“Megan claimed she felt threatened by Macy, but that dog was a sweetheart,” a digusted source tells the National Enquirer. “She wouldn’t hurt a fly.”

“Brian adored Macy and refused to give her up for the longest tie, but Megan nagged him about it until he finally gave in. He was crushed.”

Right after Brian, who is 35, agreed to place Macy up for adoption, Megan adopted a pair of “tiny toy dogs” for herself.

“It’s pretty apparent that forcing Brian to get rid of Macy was just a way of throwing her weight around,” the spy adds with a huff. “Now Brian misses Macy and regrets giving her up. Luckily for Macy, Brian found her a great new home where she’s appreciated.”
