The Australian, 27, reached a Grand Slam final for the first time in his career but came up short against Novak Djokovic in a 6-4 3-6 4-5 6-7 defeat. 7 Nick Kyrgios grabbed a beer shortly after his final loss 7 The Aussie then went to a nightclub with his girlfriend Costeen and his sister Halimah 7 Costeen stunned in matching blazer and skirt Source: Instagram @costeenhatzi 7 And Halimah got the party started with two large bottles of boozeCredit: Instagram @costeenhatzi 7 Kyrgios kept his signature red cap as he danced with CosteenCredit: Instagram @kyrgios_halimah Kyrgios accused a spectator of having 700 drinks in the final, but was quick to down a well-deserved bottle of beer as he left SW19. The tennis star later went to a London nightclub with his girlfriend Costeen Hatzi and his sister Halimah. Kyrgios was holding a red Jordan cap as he partied – an element that has proved controversial in the past fortnight for breaching Wimbledon’s strict all-white policy. And she appeared to be having fun by Costeen’s side as the pair watched champagne bottles fitted with sparklers go up in the air. Costeen was also loving life after seeing William, Kate and Prince George, as well as Tom Cruise earlier in the day. And she looked stunning in a white crop top, beige blazer and matching skirt as she headed to the club. Kyrgios’ sister, Halima, made the most of the occasion and posed with two bottles of alcohol in the early hours. The Australian wore a tight blue dress and was filmed dancing and singing along to the music. 7 There was also tequila on offer for the party animalsCredit: Instagram @kyrgios_halimah 7 Kyrgios celebrated reaching his first grand slam final in styleCredit: Instagram @kyrgios_halimah JOIN SUN VEGAS: GET A FREE £10 BONUS WITH 100 PLAYS AND NO DEPOSIT REQUIRED (T&Cs Apply) He was also delighted to spot celebrities around Wimbledon, including movie star Cruise.
