Suddenly shy? Rita Ora wraps up in oversized shearling coat as she heads to Heathrow airport... after flashing underboob at Fifty Shades Darker premiere

She pulled out all the stops for the Fifty Shades Darker premiere in London on Thursday night. 

And Rita Ora decided to take a break from glamour as she arrived at Heathrow Airport to jet off to her next work commitments on Friday. 

The 26-year-old singer shielded herself from the intense British chill in a brown shearling coat as she exited the vehicle and scurried indoors.

The British-Albanian star utilised one hand to hold the statement coat in place in an attempt to warm up. 

The garment parted ways slightly to unveil her all-black ensemble underneath which consisted of wide-leg trousers and a matching top. 

Despite the miserable grey weather, the RIP songstress donned a pair of shades and tied her locks into a chic top-knot. 

A red chained handbag was also draped on her shoulder and she completed the look with a pair of trainers. 

It was a different story the night before as Rita dazzled on the red carpet in a show-stopper gown. 

The America's Next Top Model host looked sensational in a figure-hugging navy dress that featured a keyhole at the bust to serve up an eyeful of underboob.

It was high in glamour, featuring a bejewelled design right across the bust, where the neckline was cut into a halterneck.

She then made a glamorous quick change into an all-white ensemble - including a turtleneck jumper, trousers and blazer. 

Musician Rita is back to reprise her role of Mia in the second film of the Fifty Shades franchise.

Mia is the sister of central character Christian Grey, but fans will remember that Rita was mercilessly ridiculed for having only three lines in the final cut of the first film.

Rita's fanbase are no doubt hoping to see the actress in a more substantial part, this time around.

In the Fifty Shades series, Jamie Dornan plays the part of Grey, an enigmatic billionaire with a penchant for BDSM.

Meanwhile, actress Dakota Johnson plays Anastasia Steele, an ingénue who falls into Grey's world of weirdness. 

Meanwhile, speaking on 'Watch What Happens Live' on Thursday, Rita said when pressed on her relationship with Calvin: 'We're good friends.

'Everybody uses social media how they want. I choose not to, so that's just my personal way to express myself, but everybody does their own thing.'

Shortly after their split, Calvin started romancing fellow musician Taylor Swift and, although seeing her former flame with someone else killed her, the 26-year-old singer tried to train herself to 'take it with a pinch of salt' and move on with her own life.

She explained: 'I don't really read magazines anymore that much, but to be honest it's kind of like obviously. But a usual break up you don't really see your ex all over the place. But, you know, you just kind of take it with a pinch of salt and keep going with your own life and make the most of who you are.'

Rita dated Calvin for just over a year when things came to a halt in 2014 and, although the hunk attempted to keep things amicable by wishing her all the best in the future, fans speculated that Justin Bieber had caused their split because the now-23-year-old heartthrob had reportedly become 'affectionate' towards the beauty in the studio.

However, Rita - who has also been romantically linked to Lewis Hamilton - is adamant she and the 'Sorry' hitmaker are just 'friends' and were working on music together.

She explained during her appearance on the show: 'We're just friends. Just musicians vibing. We had a few drinks, just musicians jamming out.' 

However, she soon stressed she was 'good friends' with Calvin on Watch What Happens Live, adding: 'I don't keep grudges with anybody.

'Everybody uses social media how they want — I choose not to, so that's just my personal way to express myself. But everybody does their own thing,' Rita said diplomatically.

She refused to say anything when asked if she had dated Zayn — instead saying she felt 'completely roasted' by the dating questions — but then insisted she was 'just friends' with Justin Bieber.

When asked if she felt she had 'dodged a bullet' by no longer being with Rob Kardashian after seeing his troubled life on the Rob & Chyna show, she clapped as she insisted: 'Nothing but positive energy from me — congratulations to the family.'
