The Tik Tok singer stepped out in the Venice Beach area looking slightly plumper than usual and her choice of ensemble was largely to blame.
The 25-year-old donned an unflattering white lace mini dress as she took a stroll along the famous boardwalk, the outfit barely covering her modesty.
As the cut-out design skimmed her upper thighs, her black underwear was visible beneath the shapeless frock.
The star was clearly not ready for her close-up, holding an over-sized and very eye-catchingly designed tote bag in front of her.
Ke$ha cleverly used the multi-coloured carrier to conceal her sensitive areas such as her stomach and thighs, with extra coverage from her boyfriend and friends who surrounded her in a huddle.
Her frame has certainly changed since a making a show-stopping appearance at the 2010 MTV Awards, showing off perfectly toned pins.
She made a more conscious effort to cover up at the Versace for H&M fashion event in November though, hitting the black carpet in a full-length leopard print number.
The often highly-styled performer’s low-key look didn’t go down a treat especially as she teamed up her off-the-shoulder doily-style gear with mismatched grey and black espadrille shoes.
As she takes time out at home in Los Angeles to focus on her song writing, Ke$ha is taking advantage of her downtime.
As she hid behind large sunglasses and displayed straggly locks, her two-toned hair could have done with a touch-up.
In a couple of months’ time, the singer will be getting ready to promote her second album, which is due for release in May.
She has spent the last year working on her new offering and as she confirmed the release date, she said: 'I want to take enough time to make sure it's the reinvention of pop music.
'That's the ultimate goal, to reinvent pop music. So I'm planning on taking as much time as I need, but May sounds about right.'
