Johnny Galecki, Jim Parsons, Kaley Cuoco and The Big Bang Theory have reunited for one last hurrah ahead of the series finale.

The team rallied at New Yorks Carnegie Hall for the Upfront season of the Big Bangs Network CBS, and were greeted by dozens of fans who were eager to catch a glimpse of them before the series ends forever tonight.

Kaley looked pretty in pink as she snapped selfies with her fans, while Jim Parsons also arrived in a dapper suit and tie.

Johnny, who plays science nerd Leonard, had shrugged off his baggy clothing for a black and navy tailored suit, and wore sunglasses as he signed autographs with a cigarette in his mouth.

Mayim Bialik wore a white dress as she posed for selfies, and later grabbed a group picture of the gang all together once more as they finish their victory lap ahead of the series finale.

In celebration of the shows achievements, the team arent going to go quietly as network CBS dedicates an entire evening to the shows honour tonight.



Starting with airing the final two episodes back-to-back, they will then air the season two finale of the spin off show, Young Sheldon, before Kaley and Johnny Galecki (who plays Leonard) leads a retrospective on the shows history.

The last two episodes – The Change Constant and The Stockholm Syndrome – will see the gang undergo a massive shake-up as Leonard and Penny hide something from their pals.

Whatever happens, we know its going to be an emotional one, seeing as the shows writer Chuck Lorre broke down in tears on its completion.

Though one major question needs to be answered before they say goodbye for good –
