Lady Gaga and her fiance, Taylor Kinney, have reportedly called it quits.

According to TMZ, sources say the couple ended their five-year relationship earlier this month. The reason for the break-up is unknown at this time.

Observers say the 'Chicago Fire' star and pop singer have been noticeably absent from each other's lives at events and social media lately.

Gaga is in Cabo right now, and was spotted without her engagement ring last week in Malibu.

Kinney proposed to Gaga on Valentine's Day in 2015, but a wedding date was never publicly announced.

The former couple have participated in Chicago's annual Polar Plunge, benefiting Special Olympics Chicago, in the past. It is unknown if they will continue the tradition now that they are no longer together.
