Yikes! Lily Allen may have accidentally gotten some Australian cops in trouble over the weekend.

According to TMZ, the 'Sheezus' singer was being escorted through an Australian airport by police when she jokingly asked one of the officers to handcuff her. The policeman complied, and soon after Allen posted the funny picture on Instagram -- which is when the trouble started.

As the site reports, the Australian Federal Police soon launched an investigation about the incident, noting the breach in protocol but reportedly claiming that the officers were "caught in the moment."

For her part, Allen has deleted the picture in question from her Instagram account -- but because this is the Internet, the photo still exists online. You can check it out here.

While it is unclear whether or not the police were in contact with the singer about the investigation, she has her career to focus on: Namely, her recent music video for 'As Long As I Got You' and joining Miley Cyrus on the Bangerz Tour.
