Pop superstar Lady Gaga is offering a $US500,000 ($A628,155) reward for the return of her French bulldogs Koji and Gustav that were stolen in Hollywood, a source familiar with the matter says, after reports that her dog walker was shot.
Gaga, whose recent performances included singing the national anthem at US President Joe Biden's inauguration last month, has been in Rome filming a movie.
Her three French bulldogs remained in Hollywood, the Daily Mail reported.
The outlet said Gaga's dog walker was walking the dogs on Wednesday evening when he was shot.
The third dog, Miss Asia, escaped and was later recovered.
Shortly before 10pm on Wednesday, a male gunman wielding a semi-automatic handgun shot a male in his 30s in Hollywood and fled in a white vehicle, stealing two French bulldogs, Los Angeles Police Officer Drake Madison said.
Fire department paramedics took the male victim to a local hospital in unknown condition, Madison said.
The source close to Lady Gaga, who spoke on the condition of anonymity, said the singer was urging anyone who has the dogs to contact the email email@example.com to return the dogs and retrieve the reward, no questions asked.
