Piastri appears to cut radio as Zak Brown speaks after Singapore GP

Piastri, who had made it clear to the team he was upset at making contact with teammate Lando Norris at the start, with the Brit overtaking him in the early stages of the race at the Marina Bay Circuit.

Adding to the frustration of the 24-year-old – who finished behind Norris – was a lengthy pit stop later in the race.

Despite the setbacks, Piastri finished in fourth place. However, it was his reaction after the Grand Prix that seemed to capture the attention. The championship leader, while driving his car into Parc Fermé cut off a radio message from team Brown, who was congratulating him for the team's successful defense of the Constructors' championship.

Brown earlier reacted to the overtaking incident involving Norris and Piastri, describing it as “hard racing” during his post-race media interaction.

The 53-year-old also highlighted that the team would review the incident properly during their post-race debrief.

The incident left Norris with a slight dent to his front wing endplate; however, it did little to affect the outcome of the British driver’s race.

McLaren have promised to review the incident away from the celebrations at winning the team's back-to-back titles.

Piastri also appeared to miss out on the podium celebrations following the Singapore Grand Prix. The Woking-based outfit clinched its second consecutive Constructors’ crown following the points haul at the Marina Bay race.

The Australian, was initially absent while the team celebrated their feat under the Singapore sky.

Piastri would eventually join in on the celebrations after he completed what appeared to be his media duties following the race.
