Los Angeles, California - Travis Barker was hospitalized for unknown reasons Tuesday, not long after putting up a worrying tweet.

As multiple news outlets reported, the 46-year-old drummer showed up at West Hills Hospital in Los Angeles, California Tuesday morning.

Later, an ambulance took the musician to Sinai Medical Center in Los Angeles. According to TMZ, his wife, Kourtney Kardashian, followed the ambulance in her own vehicle.

It's still unclear what prompted this trip to the hospital – or, for that matter, what the star's current condition is.

Tuesday morning, Travis had tweeted, "God save me."

This could just be a reference to a song on Machine Gun Kelly's new album, Mainstream Sellout, which the Blink-182 alum helped produce, but in the context of this latest development, it's still causing a lot of concern.

As of Wednesday morning, Travis' condition is still unclear.

Tuesday afternoon the drummer's 16-year-old daughter, Alabama Luella Barker posted an Instagram story asking followers to "Please send your prayers."

His wife Kourtney, on the other hand, shared a link to an article about healthy boundaries and having space in relationships on Twitter. They held a lavish wedding last month in Portofino, Italy.

This isn't the first time Travis has been hospitalized. In 2008, he was treated for third-degree burns on most of his body after surviving a plane crash that killed six others. A decade later, he was admitted with blood clots in his arms.
