Lady Gaga is poised to hand over a $500,000 reward to a mystery woman who returned her beloved French bulldogs kidnapped in a violent street robbery near her home in Hollywood. Koji and Gustav, thought to be worth up to $10,000 dollars each, were given in at a downtown LAPD Police Station by an unnamed woman late on Friday night. Authorities believe the woman who handed the dogs in was "uninvolved and unassociated" with the attack - but she is still eligible for the "unconditional" $500,000 and is said to be in contact with Gaga’s representatives. “If you bought or found them unknowingly, the reward is the same,” Gaga had said in a post confirming the hefty sum before the dogs were handed back on Friday. The violent abduction on Wednesday saw the singer’s dog-walker and close friend Ryan Fischer shot in the chest. Gaga's third dog named Miss Asia escaped the attack and was later found by police. The singer, whose real name is Stefani Joanne Angelina Germanotta, has kept silent since the dogs were handed into police. But her reward offer has raised eyebrows.
