Cara was spotted visiting Rihanna's hotel room after the Twickenham show, before the pair headed to London nightclub, Bijous, where they partied until the small hours.
RIHANNA'S ON FIRE! CHECK OUT HER TOUR PHOTOS
Rihanna was dazzling as she stepped out in a holographic look, teaming a sequinned Stella McCartney crop top with Acne Generic Girl ripped jeans, an iridescent silver Stella McCartney clutch with matching strappy heels, while Cara kept it cool in burgundy skinny jeans and a leather and fleece bomber jacket over a grey cam, accessorising with gold pendants.
Cara and Rihanna have been respectively documenting their friendship in a frenzy of Instagram pics as the pair have hung out for the singer's Diamonds World Tour - the first pic coming from Rihanna, who tweeted: "Look who just joined the #diamondsworldtour @caradelevingne #thuglife", at the beginning of June.
Clearly loving the show, Cara tweeted from gigs in Barcelona, Montpellier and Lyon, before the tour hit the UK where the British model tweeted a picture of herself with hordes of excited Rihanna fans.
With the tour not leaving UK shores for another few days, we can't wait to see more BFF selfies of the party-hard pair.
