Australian Open hopeful Alexander Bublik showed his cheeky side during his Adelaide International quarter-final against Lorenzo Musetti by stealing a supporter's crisp at one point.
Bublik is one of the more colourful characters on the ATP Tour and regularly got into trouble during his matches.
He caused a stir at last year's US Open when he was caught on camera saying in Russian "I am sick of giving careers back to disabled people" during his match against Dominic Thiem.
Bublik has also previously stated that he "hated tennis" earlier in his career.

But the enigmatic 26-year-old can be a joy to watch when he's playing with a smile on his face.
And that was evident in Adelaide on Wednesday during his clash with Italian star Musetti.
Bublik had taken an enthralling opening set against Musetti before his opponent rallied back in the second.
The No 4 seed went a break up in the second and Bublik appeared to let his hair down at that point.
While on serve and 4-1 down, Bublik won three consecutive points with audacious drop shots before winning the game with an underarm serve followed by a tweener-winner.
Bublik lapped up the applause from the small crowd as he took a bow at the baseline.
That inspired a fightback from Bublik to force a second-set tiebreak, but Musetti managed to force a decided set.
With the match finely poised and Bublik with a break point opportunity in the fourth game, Musetti hit a smash at the net to leave his opponent scampering across the baseline.

Bublik was unable to get there in time, but he also couldn't stop himself before running into the crowd.
Fortunately, Bublik was able to avoid any danger as he jumped up in front of surprised spectators in the front row.
One person was sat with a bag of crisps on his lap next to where Bublik ended up and the tennis star cheekily helped himself to a treat before returning to the court.

Musetti remained on top though and broke his opponent soon after and gave himself a match point, but Bublik managed to save it and pull off an extraordinary victory.
He now faces British tennis star Jack Draper in the semi-final with either Sebastian Korda or Jiri Lehecka awaiting in the final.
Bublik has also been given a favourable draw for the Australian Open as he'll face either a lucky loser or a qualifier in the first round.
But the No 31 seed could meet Carlos Alcaraz in a mouthwatering third-round tie if they both make it that far.
