LeBron was clad in a dapper double-breasted suit as he gave a speech at the event, and was joined by his entire family on the court for the ceremony before the Bucks game.

His wife Savannah, 36, stunned in a taupe co-ord with crystal details, and held an Hermes handbag in her hand.

She wore her light blonde tresses parted on the side and cascading down in loose waves.

Also at the ceremony were the couple’s three children sons Bronny, 18, and Bryce, 15, and daughter Zhuri, eight, as well as LeBron’s mom Gloria Marie James, 55.

James dedicated more time of his ceremony to his family, introducing them as ‘his starting five.’

‘You know, my two boys – Bronny, Bryce – my daughter Zuri. My mom, Gloria, my wife, Savannah, like this is my starting five,’ he added.

‘And I wouldn’t be able to do the things that I do on a day to day basis, I wouldn’t be out, I wouldn’t be able to come on this court and showcase my talent to you guys every single night, if I didn’t have the support, and I didn’t have the commitment from my family that allowed me to do the things that I do.

‘So, you know, I wouldn’t be standing up here. I wouldn’t be who I am. I wouldn’t be able to inspire so many people all over the world.

‘I wouldn’t be able to inspire the Laker faithful. I wouldn’t be able to inspire, nobody if I didn’t have the sacrifices and the commitment from my starting five right here. So please give them a round of applause. Please.’

Just two days ago, James knocked down a fadeaway jump shot from the left elbow that officially saw him pass Kareem for first on the all-time NBA career scoring list.

Fans shelled out thousands to secure a seat at Crypto.com arena to witness history, and James didn’t disappoint them – putting on a show by dropping 38 total points to seal the record.

James went into the game against the Oklahoma City Thunder only needing 36 points to overtake the record of 38,387 – which was set by Abdul-Jabbar in 1989.

Unfortunately, the record was the only moment of triumph for Lakers fans – as they watched the home team lose 133-130 to OKC.
