It beats the Circus! Life is a roller coaster for Britney Spears as she enjoys family fun day at Hollywood theme park

Her life has had plenty of ups and downs.

And it turned into a roller coaster for Britney Spears after she took a thrill ride with her children at a Hollywood theme park on Sunday.

The daring 33-year-old looked in her element as she sat next to her brother's daughter as they rode a spinning carousel at Universal Studios.

To the absolute joy of her fans, the saucy 33-year-old captioned the short Instagram video of her thrill ride: 'Sunday funday at @unistudios with the family!'

Britney was accompanied by her sons Preston, 10, and Jayden, 9, who were both sired by her ex-husband Kevin Federline. 

She was also joined by her grinning older brother Bryan, 38, and his daughter Lexie. 

The Baby One More Time favourite later posted a picture of the cute quintet standing outside at the park's entry sign.

Of course Britney does not have to worry about the cost of admission to funfairs given how much she has raked in headline Las Vegas's Planet Hollywood casino.

She has certainly hit the jackpot, as her stint on the Axis Theater stage has reportedly earned her $35 million, $30m for her first round of gigs which started back in December 2013 and $5m more for her recently announced two year extension.

She has also literally turned her successful Las Vegas residency into a money making machine, as on Thursday it was revealed that the 33-year-old has landed her very own slot machine. 

However she has certainly not slowed down in her activities away from Sin City, as earlier this week she pranked wannabe bodyguards on Neil Patrick Harris's NBC variety show Best Time Ever.
