She was understandably embarrassed when she was filmed throwing up onstage.

And after watching it on YouTube on Monday, Lady Gaga admitted she 'cried a little' when watching herself in agony.

Now in London during a break in her Born This Way Ball world tour, the singer was taking things easy as she left her hotel.

The New Yorker was her usual flamboyant self as she dressed head-to-toe in black, with a matching hat.

She looked like she was in mourning, or perhaps getting ready for Halloween in a black blouse, maxi skirt and jacket.

At one point, the hat fell off her head, prompting an onlooker to pick it up for her.

Earlier on Monday, she tweeted she had watched the online video of her on-stage puke, which was filmed in Barcelona on Saturday.

She tweeted: 'Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan “Vomit” Lake.

'I still hit my routine mom!! 🙂 Thank
goodness for the Dorchester… I need some tea, I think I just cried a
little watching that.

'It WAS pretty metal. Belligerent throw up during sax solo amidst epic power ballad about glory atop medieval castle #metal.'

Things only got worse for the singer as some of the 25,000 strong crowd poked fun at her over her recent 25lb weight gain.

Gaga was showered with sausages but
took the jibe in her stride as she tweeted after: 'SPAIN, you took the
p*** outta me. Thats some hard bodied pop stuff. I'll never forget
tonight Barcelona. FOREVER'. (sic).'

After arriving in London on Sunday, Gaga launched her new perfume in Harrods.

She is set to enjoy a few days off from her gruelling 11-month world tour before resuming it in Mexico on October 26.
