Britney Spears' Las Vegas concert has been given quite astounding reviews as the "Work B*tch" singer has been able to do amazing shows since her Las Vegas shows had begun.

Celebrities filled the crowd, from Miley Cyrus to Adam Lambert and Selena Gomez along with guest stars Mario Lopez who were also brought on stage for Britney's "Freakshow".

Though most of the celebrities and fans said that Britney has improved a lot since her "head shaving" days, it seems like she wasn't able to impress everyone with her "Britney Spears: Piece of Me" concert in Las Vegas.

Katy Perry wasn't the least bit fascinated by Britney's concert as reported by TMZ.com. The site had reported that Katy Perry said she would 'rather watch dry paint' then watch Britney in action.

We understand that Britney ain't no John Mayer and she would least be interested in Britney's dancing and performance but most celebrities such as Miley Cyrus can attest to Britney's amazing performance. The "Adore You" singer, Cyrus was dancing to almost every Britney hit along with all the other celebrities and fans.

Katy Perry and Britney Spears may not be 'close' friends as she and Rihanna are but saying "dry paint" is better than Britney Spears is quite an insult to the "princess of Pop".

It may be another fabricated story run by TMZ.com and or just a spoof on Katy Perry's lack of energy at the Britney Spears show in Las Vega, where Britney performed all her timeless hits including "I'm A Slave 4 U", "(Hit Me) Baby One More Time", "(Drive Me) Crazy" and many more hits.

Katy Perry may be having a great time with her secret engagement to John Mayer and whatnot but certainly she would be much platonic if she didn't find Britney's show entertaining enough for her as everyone knows Britney can certainly perform.

The star still have more shows to do as she currently resides in Las Vegas performing at Planet Hollywood.
