Rita Ora cuts a sombre figure in workout gear... after paying tribute to late friend Avicii at Netherlands festival

She's been mourning the tragic loss of her friend Avicii, who sadly passed away aged 28 earlier this month.

And Rita Ora cut a sombre figure when she stepped out in London on Thursday, leading a gym in Kensington on Thursday in an all-black ensemble.

The singer, 27, flew under the radar during her outing, hiding underneath a baseball cap and shades.

Rita was casually clad in a black jumper, adding a touch of glamour thanks to silver chain necklaces.

She wore a leather bag over one shoulder as she left the gym, going make-up free after her workout. 

The star was clutching her phone as she headed off home, with cordless headphones in her ears.

She paid tribute to the late DJ as she took to the stage at the 538Koningsdag Festival in the Netherlands last Friday, moving the crowd to tears.

The star burst into tears as she held a minute's silence for the producer, who was found dead aged 28 in Muscat last week, before performing the track they worked on together.

Rita told the 40,000-strong crowd ahead of her performance: 'I'm going to say something which is really, really special because it's going to be hard for me to sing this next song and I'll tell you why.

'I had the honour of collaborating with somebody who changed my life and he's a really good friend of mine and I heard some DJ's playing some of his music earlier.

'I haven't sang his song that we did together, ever since he passed away- until today.

'So it's going to be very hard for me to sing this next song. I'm obviously talking about the incredible Avicii.'

The Anywhere hitmaker told the crowd her song Lonely Together was the last song he released and asked them to pay tribute to her 'dearest friend' with a minute's silence.

In the footage, Rita struggled to hold back the tears as she bowed her head in memory of the world-renowned musician.

Rita ensured all eyes were on her on stage as she performed the energetic track.

Clad in a black and gold glitter striped tracksuit, the singer flashed her washboard abs and plenty of underboob during the high-octane show.

The This Is How We Do star slicked her hair back into a high ponytail and accentuated her glowing complexion with a slick of black eyeliner and nude lip. 

Following Avicii's death last Friday, Rita was one of the many celebrities to take to Twitter to pay tribute to the late DJ.  

'Dearest friend': 'I had the honour of collaborating with somebody who changed my life and he's a really good friend of mine and I heard some DJ's playing some of his music earlier'

She penned: 'I have no words. I remember how amazing it was to make Lonely Together and it felt like just yesterday we were talking.

'Condolences to Avicii's family, friends, and the fans who supported him. May he rest in peace. Gone too soon. I'm devastated. Heartbroken.' 

Following the news of his death last Friday, Rita put her heartache to one-side as she attended the Blondey McCoy and Arena Homme + launch, shortly after she paid tribute to the star on social media.

However, shortly after the event, Rita looked downcast as she dined at London's Scott's Restaurant in Mayfair.  

The body of the Swedish-born producer, who is known for his EDM hits Wake Me Up, Levels and Hey Brother, was found in Oman, a publicist confirmed.

The cause of Avicii's death is not yet known.

Avicii, born Tim Bergling, quit touring in 2016 due to battles with his health, suffering from acute pancreatitis and had to have his gallbladder and appendix removed in 2014.
