Tyrese Haliburton's stunning girlfriend celebrates the Pacers' NBA In-Season Tournament semifinal win after the point guard stole the show with 27 points to help Indiana beat the Bucks

Tyrese Haliburton's stunning girlfriend, Jade Jones, celebrated the Pacers' NBA In- Season Tournament semifinal win on social media, after the point guard stole the show to help Indiana beat the Milwaukee Bucks with a 27-point performance.

Jones cheered on the 23-year-old All-Star on Thursday, from the T-Mobile Arena in Las Vegas - home of the NHL's Vegas Golden Knights - as her beau also put up 15 assists, committing zero turnovers against his hometown team. 

She was spotted wearing a snakeskin bodysuit with Halliburton's last name on the front, as seen in photos shared on her Instagram page. 

'Go pacers,' she captioned her story - an overhead picture of the tournament's first ever semi-final. 

Jones also posted a behind-the-scenes snap of the 'Inside the NBA' crew filming part of Thursday's show. 

Haliburton and his college sweetheart have been locked in romantically since their days at Iowa State. Jones was a cheerleader while her partner averaged a little over 10 points a game in his two-year span on the Cyclones' men's basketball team. 

Together, they celebrated their four-year anniversary in April. 

Haliburton and the Pacers will go on to meet LeBron James and the L.A. Lakers for the NBA's In-Season Tournament title on Saturday night. Both teams are 6-0 in the event.

James has won four NBA titles and been to the NBA Finals 10 times. He is the NBA's career leading scorer and has a slew of accolades. 

Haliburton is essentially just starting out; he was an All-Star last year, got a rookie max extension from the Pacers last summer that will be worth at least $205million and has emerged as perhaps this season's breakout star.

'He's a great player,' Milwaukee's Giannis Antetokounmpo said. 'But to be able to have 25 points plus, 15 assists and not turning the ball over, which I had no idea about it, speaks a lot. Speaks volumes about the way he's playing this year.'

The Lakers-Pacers game won't count in the standings, since it'll essentially be the 83rd game in an 82-game season for both teams.

Players from both teams have clinched $200,000 each for making the final; two-way players get half that much. Players on the winning team get $500,000 apiece, so there's roughly $4.5million at stake in Saturday's game.

The winning team also gets the NBA Cup and all players from the championship team get medals.

Pacers coach Rick Carlisle said: 'We have a dream as an organization to be an NBA championship organization. They won three ABA titles, and that's a big deal. Winning an NBA title is a dream that's reachable, but it's got to be a dream where people can focus on how it's reachable, and we're showing signs of that. We're not there yet. 

'We're showing signs, and we're a dangerous team.'
