'The Essential Britney Spears' Marks Another Greatest-Hits Album For The Singer, Will Arrive Before New Studio Project

Britney Spears has been teasing a new album for months, and for a hot second we almost thought a release date was nigh. But alas, no such luck. The singer instead announced she will release another greatest-hits album.

Spears has a few of those already. The first, "Greatest Hits: My Prerogative," arrived in 2004 following the singer's fourth album, "In the Zone." A remix compilation came the following year, and in 2009 "The Singles Collection" updated the previous best-of anthology. We received another remix effort in 2011, and now a third greatest-hits project is set. Anyone spot the trend?

No need to fear too much, though -- Spears says she's still hard at work on her eighth studio album. The singer tweeted Thursday night that it's on the horizon.

In the meantime, "The Essential Britney Spears" will go on sale Aug. 20 as a Walmart exclusive. The two-disc release features a chronological tracklist that spans "...Baby One More Time" to "Scream & Shout."
