Leo kept it smart and dapper with a dark blue suit and tie and his hair neatly slicked back.

The actors happily posed together for photos and joined each other for interviews with reporters on the red carpet, while also being pictured laughing around together at one point.

It comes after Jennifer addressed reports that she was paid a whopping $5m less than her male co-star to star in the film, despite being billed as the lead actor and the script being written with her specifically in mind.

Speaking in a new interview with Vanity Fair, Jennifer was asked about the pay discrepancy, and she insisted she is ‘very happy’ with her deal. The deal in question is a pay slip of $25m (£18.7m) to star in the flick, an absolutely mind-blowing amount of money for most people, but still significantly less than co-star Leo.

He was paid $30m (£22.4m), meaning Jennifer was paid 83 cents for every dollar given to Leo.

When asked about the deal, Jennifer admitted she ‘saw’ the pay discrepancy but appeared to accept that ‘Leo brings in more box office than I do’.

She added: ‘I’m extremely fortunate and happy with my deal.’

Jennifer, who won the best actress Oscar for Silver Linings Playbook in 2013, acknowledged that it’s ‘extremely uncomfortable’ for women to ‘inquire about equal pay’.
