Britney Spears has boasted her new album is the "best thing" she has done in a "long time".

The 'Work Bitch' singer is "proud" of her forthcoming LP because of how different it is from her seven previous pop releases.

Britney is still in the process of completing the album and is prepared to spend the rest of the year or longer working on her fresh collection of tracks so they are perfect for her fans.

Speaking to V Magazine about her upcoming record, the 34-year-old star - who is also busy performing her 'Piece of Me' concert residency at the Planet Hollywood resort and Casino - said: "I'm proud of the work, and it's very different; it's not what you would think at all. But I'm not rushing anything. I just want it to be done right, so that my fans will truly appreciate it. I would much rather have it be completely how I want it to be, whether that takes another year for me to do, or two months. I have no idea at this point.

"Honestly, I'm just particular with this record. It's my baby, and so I really want it done right."

She added: "I just know that the direction I'm going in is so good. It's the best thing I've done in a long time."

Britney's manager Larry Rudolph has previously compared her new songs as comparable to R&B singer The Weeknd.

Larry said: "It's different, it's a turn. The last few albums have been pretty straightforward pop. This is almost like if you can imagine Britney meets The Weeknd. It's got a really interesting vibe, it's a lot of really cool stuff."

Although there is no set release date for the hitmakers new musical wonder Larry has teased it will be later this year.

Britney is the cover star of V Magazine's 100th issue which comes out on Tuesday (08.03.16) and for which she was shot by Mario Testino.

Taking to Twitter to share her cover, she also tweeted: "On stands this week!! @vmagazine and @MarioTestino know how to make mag cover magic. #V100 (sic)"
