So it's understandable that Katy Perry would welcome a rare break from her hectic promotional schedule to indulge in some of the simpler pleasures in life.
The pop star, who turns 29 on October 25, was clearly enjoying a glam-free day to herself as she ran some errands in Beverly Hills without even a touch of make-up, on Wednesday.

The California native sported a pair of rubber thongs as she displayed her lean calves in pedal pusher exercise tights.
Matching her bottoms was a long grey polka dot tunic that accentuated her slim 5ft7in frame.
Completing her ensemble was a pair of dark sunglasses as she tied her hair up with a brightly patterned piece of cloth.

Despite her low key appearance, Katy is currently riding high.
Her latest number one single Roar has blasted past all of her previous sales records - leaving Lady Gaga at number three with her single Applause.
And while Roar has her fans in a frenzy with images of tigers, Katy's inspiration for writing the song comes in the form of a much smaller feline.
The songstress revealed on Tuesday: 'Secretly... I love how when I wrote #ROAR I was just trying to write a song about being a mega cat lady.'
Adding: 'Shhh, don't tell anyone.'

Roar sold over 557,000 copies just last week to beat out Lady Gaga for the number one seat on the charts, which also blasts past Perry's previous record of 509,000 for 2010's Firework, according to Billboard.
Roar is the vanguard single for Perry's upcoming album, Prism.
Meanwhile, Katy recently revealed the circumstances for her brief split and eventual reconciliation with her beau John Mayer, after the two released their duet Who You Love.

The romance was sparked after Katy finalised her divorce from ex-husband Russell Brand in early 2012.
Of the short-lived break-up with Mayer, Katy confessed in the September issue of ELLE UK: ‘He pulled away. That was a big hello for me.
‘I realized I could lose the person I loved and I had to deal with some things, issues I think a lot of women have. You can be strong in one aspect of your life but submissive in another.’
