Kokkinakis takes joking shot at Bernard Tomic over cringeworthy engagement prank video

Australian Open doubles champion Thanasi Kokkinakis ribbed compatriot Bernard Tomic on Thursday after the latter posted another cringeworthy prank video on Instagram.

Bernard, 29, pranked his sister Sara by calling her and saying he was engaged to a new girl called Ashley. And Thanasi, who won the Australian Open Men's Doubles with Nick Kyrgios last month, didn't seem too impressed.

'These gotta stop BT,' Thanasi wrote underneath Bernard's post, adding a face palm and crying with laughter emoji.

In the clip, Tomic rang his sister to tell her he was engaged after he lost a bet with his female friend Ashley.

'Hey Sara, guess what, I'm getting married. I found the love of my life. I know it's quick but don't worry about it,' Tomic began.

His sister Sara was completely shell-shocked and not happy with the news.

'What do you mean bro, what are you on about? Bernard, you're going to give us all a heart attack again. You just got out of a serious relationship, what do you mean,' Sara said.

She added, referring to his ex-girlfriend Vanessa Sierra: 'I've got one question for her... Do you do OnlyFans?'

Ashley replied: 'Not anymore... I love him. Can't wait to meet you! See ya sister-in-law!'
