Remember all those jealousy-inducing bikini pics Britney Spears posted a few months back from her vacation in Hawaii? Turns out it wasn't exactly the most relaxing trip of her life.

Speaking to Radio One DJ Scott Mills in an interview airing Wednesday, Aug. 24, Britney revealed she nearly drowned when she found herself engulfed in what she described as "six foot waves" in the strong Hawaiian surf.

"I went out and I thought it was like a wave pool, and I was like, 'This is so nice and refreshing and just ­beautiful," she said (via the Daily Mail).

"But the thing I didn't think about is when you come back, the waves really come in hard. I got sucked under for like five minutes. I almost drowned. And I'm like, 'Where is my security? They're just going to let me die here.' And then I came in again and another wave took me under."

She managed to get out of the water before things got worse but the experience left her shaken.

The DJ also asked Brit-Brit if there was anything in her life she would have done differently with the benefit of hindsight.

"Never get married, number one. That's probably the best advice I could give myself," said the singer, who married the father of her sons, Kevin Federline, in 2004 after having a 55 hour-long marriage to Jason Alexander annulled the same year.

Britney's slated to release her ninth studio album, "Glory," on Friday, Aug. 26.

"We're having fun right now," she told E! News in November after she confirmed plans for the recording. "I'm working with some women who are amazing writers. I have ballads and, of course, dance music - fun, cheeky, sexy stuff."

She later told V magazine the new album is "the best thing I've done in a long time. I'm proud of the work, and it's very different; it's not what you would think at all."

The first single off the album, "Make Me," featuring G-Eazy, landed July 14 and promptly knocked her ex-boyfriend, Justin Timberlake, out of the No. 1 position on the iTunes charts.
