Since the release of "Ultraviolence," Lana Del Rey has been absent from the public eye, other than her brief appearance on James Franco's Instagram account last month.

Lana Del Rey fans will be disappointed to know that the 29-year-old has canceled all of her upcoming European appearances for "Ultraviolence," according to E! Online.

"For medical reasons independent of our will, the artist has been forced to cancel all promotional activities planned in Europe over the coming days," the Universal Music label said in a statement to MTV.

Lana Del Rey is reportedly hoping to reschedule her prior agreements later on this year.

The "Brooklyn Baby" singer also canceled two private shows in Paris for Virgin Radio listeners last week, according to the NY Daily News. The "Young and Beautiful" songstress has also noticeably gone silent on Twitter since the end of July.

Although Lana Del Rey isn't the most active on social media, the recent cancelation of her European tour has caused fans to worry about the brunette beauty.

"I'd been sick on tour for about two years with this medical anomaly that doctors couldn't figure out. That's a big part of my life. I just feel really sick a lot of the time and can't figure out why," the "Ultraviolence" hitmaker revealed to The Fader.

Del Rey had made headlines at the end of July for opening up about her track "F**ked My Way Up To The Top."

"It's commentary, like, 'I know what you think of me,; and I'm alluding to that," explained Del Rey.

She added, "You know, I have slept with a lot of guys in the industry, but none of them helped me get my record deals. Which is annoying."
