"Hold It Against Me" singer Britney Spears is all set to thrill her UK fans with the "Femme Fatale Tour" that starts from Belfast on Oct. 25.

The pop princess, while on a 33-date extravaganza in the U.S., wowed audiences with seductive and raunchy performances. The singer will attempt to go a little bit further for her UK fans, with dramatic costumes and hair styles, as well as sexy outfits and dance routines. Her support act during the UK leg of the tour will be Joe Jonas, of the boy band Jonas Brothers.

Spear's seventh studio album, "Femme Fatale", was named the Favorite Billboard 200 No. 1 Album, after topping charts upon its release in March. Her single "Hold It Against Me" won the Favorite Hot 100 No. 1 Song award. The singer's cheeky video for the song "I Wanna Go" was also voted Best Music Video and her recently started "Femme Fatale" tour was voted Best Tour in Billboard.com's Mid-Year Music Awards poll.

The blonde singer, who was in the news for reportedly being overweight, seems to have re-discovered her best form, particularly during her performances in Moscow.

The "Femme Fatale" show is based around an action-adventure theme, beginning with a video of the pop star being chased by police. The set changes frequently, in order to reflect the different identities Spears assumes throughout the concert. During previous tours, Britney featured in several costumes - nine in all, including an angel outfit, a kimono and a kinky leather motorcycle-gear ensemble.

"The real inspiration (for our) raunchy costumes is Britney herself. We're creating the show for her. But there's a creative script that was done by the director, Jamie King, and it's a whole thing about a femme fatale, and femme fatales throughout the ages ... she's sort of changing personas throughout the show. Britney is a very sexy girl, so everything has to be sexy," said designer Zaldy Goco, in a report by Mail Online. Goco has designed Spears' costumes for the tour. Rolling Stone magazine has called the tour her "flashiest yet".

However, despite the glam, there have been media reports stating the tour is failing to attract an audience, despite slashed ticket prices. The singer's raunchy tour hits London, Birmingham, Newcastle, Sheffield and Manchester between October 27 and November 6 but staff fear empty seats.

"It's probably about half-full. There's good availability," said an unnamed ticket-retailer, to The Mirror. The report also mentioned around 500 standing tickets were unsold and 11 seat blocks still have space. This has happened despite a cover-price offer and free deals made by discount Web site Groupon.com. Tickets originally priced at £55 (for the Birmingham LG Arena) have been dropped to £30 and only half of the 16,000 tickets for the event have sold, which is a cause for concern.

However, the singer is not mood to get perturbed.

"I don't really have anything to prove at this point. I just do it for fun and see what happens. I have a good group of people around me. We have the show at a certain time every night. The show is really fun for me, it's one of the most entertaining shows that I've ever done. There are six or seven costume changes, the dancers are just on fire and it's a lot of fun. It's a fun show," said Spears, during an event in the U.S.

After her failed marriages, stints in rehabilitation and nervous meltdowns, Spears must be hoping that the tours re-establish her star status. At present, she seems happy in a relationship with William Morris agent, Jason Trawick.

"I hear the older you get, the wiser you get and the more you know what you want. Hopefully it'll be a good year," said the singer, who turns 30 in December, at an interview with Associated Press.
