Liza Minnelli's show-stopping Oscars outfit has caused a Twitter storm as the US singer/actress matched her electric blue trouser suit with a streak of hair dye - and a rather unfortunate wardrobe malfunction.
Oscars host Ellen DeGeneres won the first awkward reception of the night when she quipped about an amazing "Liza Minnelli impersonator", a joke she followed up with "Good job, Sir".
Minnelli's attention-grabbing outfit revealed she appeared to have 'forgotten' to wear underwear, resulting in a flood of posts on Twitter.
"Liza Minnelli, otherwise known as 'Nip'" wrote one Twitter user, while another described the legend's outfit as "borderline obscene".
While many mocked Minnelli's choice of red carpet get-up, others defended Judy Garland's 67-year-old daughter for her more adventurous fashion decision, which has proved the most controversial of the evening so far.
"How cute is Liza Minnelli and her blue hair streak? At 67, why not?" read one favourable tweet, while another wondered whether she had turned up at the wrong party. "Has anyone told Liza Minnelli she's at the Oscars?" it read.
Fashion disasters at the Oscars
Fashion disasters at the Oscars
1/11 Gwyneth Paltrow (2002)
Gwyneth Paltrow is a serial offender of bad fashion choices at the Oscars and this black, transparent Christian Lacroix gown is no exception. The actress has since confessed that she should have worn a bra with the outfit, but fashion editors do not think it would make much difference to this fashion faux pas.
2/11 Celine Dion (1999)
Canadian singer Celine Dion made a bold fashion statement at the 71st Academy Awards, deciding to wear her white Christian Dior tuxedo backwards with a matching fedora and diamond-encrusted sunglasses.
3/11 Kate Hudson (2001)
Kate Hudson arrived at the 73rd Academy Awards with her then-husband Chris Robinson, wearing a lacy blue dress by Stella McCartney. Hudson was nominated for Best Supporting Actress for her role in the Cameron Crowe film Almost Famous, but lost out to Marcia Gay Harden for Pollock.
4/11 Bjork (2001)
Icelandic pop star Bjork caused waves when she arrived at the Oscars ceremony in 2001 dressed as a swan. Despite receiving a frosty reception at the time, her outrageous outfit has entered awards fashion legend and has been spoofed many times.
5/11 Faith Hill (2002)
Singer Faith Hill brought a splash of colour to the red carpet in 2002 when she was performing at the Oscars ceremony. The rainbow-coloured gown certainly stood out against the more sombre dresses on the night but it was a bad choice for such a formal event.
6/11 Uma Thurman (2004)
A dress that appeared to have been picked from a child's dressing-up box was what Uma Thurman decided to model at the 76th Academy Awards. Accessories included a gold clutch bag and a clashing turquoise belt which only served to highlight the general lack of care that seemed to have gone into the milkmaid look.
7/11 Diane Keaton (2004)
Diane Keaton deserved the label fashion victim at the 76th Academy Awards. Wearing a creation by Ralph Lauren, onlookers seemed unsure whether Keaton was trying to emulate a comedic undertaker or a circus ringmaster. Grey leather gloves, a bowler hat and an unnecessary white carnation added to the bizarre outfit.
8/11 Meryl Streep (2007)
At the 79th Academy Awards Meryl Streep failed to pull off her Far East-inspired look; instead she appeared frumpy in her take on a kimono. The outfit did however manage to be livened up by the addition of some colourful beads.
9/11 Sarah Jessica Parker (2010)
The 82nd Academy Awards saw Sarah Jessica Parker in a floor-length cream gown, perhaps more suited to a 19th century ball than the glittering Oscars. A frilly grey trim with oversized flower completed the curtain-like look.
10/11 Zoe Saldana (2010)
In 2010 Zoe Saldana took the brave decision to step out on to the red carpet in a dress that appeared to have a large, furry animal stuck to it. The bold colours of purple and lilac did not add to the ensemble, leading fashionistas to brand it a decided fail.
11/11 Helena Bonham-Carter (2011)
Helena Bonham-Carter surprised fans by opting for a revealing black dress at the 83rd Academy Awards. Adding colour to the outfit was a not-so-tasteful Union flag suspended by a red ribbon just below the knee.
Many nominees opted for far safer choices, such as American Hustle's Amy Adams, who chose a navy blue gown.
Lupita Nyong'o exceeded all expectations in a plunging pale blue dress as she arrived on the red carpet, ready to hear whether she will be taking home the Best Supporting Actress award later in the night.
