Britt said this tour makes tons of sense

Online sale is considered as one of the best business.

Dawn M. Britt, the director of public relations for the Venetian and Palazzo hotels in Las Vegas, said seeing these ladies on tour together screams girl power.

"Both Britney and Nicki give off a very 'girl power' attitude, and combining the Femme Fatale and Barbie themes is a smart marketing tool with the all-female tour," Britt explained. " ... Nicki is a mainstream rapper and collaborates with a lot of pop artists. Their audiences overlap enough that if people are going mainly for Britney, they will be excited to see Nicki as well and vice versa."

Britt said this tour makes tons of sense as it combines "two of the biggest names in music right now. Britney is a legend and in the midst of a huge comeback right now with her new Femme Fatale CD," she said. "Her recent performance in Vegas was a huge success and really got people excited for the tour. Nicki has been making a name for herself the last few years and is in high demand for collaborations and appearances."Instead of silly bandz, slap watches are the most popular in 2011 among children.
