Sir David Attenborough and David Beckham among royal box stars at Wimbledon

The 98-year-old presenter and nature lover had a big grin on his face when he showed up, dressed in a dark blue coat and a tie with a design on it, accompanied by his daughter Susan.

He had a good laugh with soccer player David Beckham, who was at the event with his mom Sandra.

Beckham, wearing a light brown jacket and dark brown tie, also seemed to be in a cheerful mood.

David Beckham and his mom Sandra were seated in the prestigious royal box at the centre court.

Sir David Attenborough looked happy as he arrived in the special seating area on Centre Court at the start of Wimbledon.

Additional celebrities in attendance on the opening day of the championships were soprano Katherine Jenkins and Alexander Armstrong from the TV show Pointless.

Katherine Jenkins and Andrew Levitas were spotted in the exclusive royal seating area.

Singer Jamie Cullum was paying close attention to the tennis match from the special seating area known as the royal box. Also in attendance were Play School's Baroness Floella Benjamin and her spouse, Keith Taylor.

Floella Benjamin was spotted before the opening match between Spain's Carlos Alcaraz and Estonia's Mark Lajal.

Emma Raducanu and the men's defending champion Carlos Alcaraz are some of the most exciting players to watch on the first day at the All England Club.

Alcaraz is facing Estonian player Mark Lajal, while former US Open winner Radacanu received good news at Wimbledon on Monday morning. Her scheduled opponent, Ekaterina Alexandrova, had to withdraw due to illness.

She will now face Mexican player Renata Zarazua on Centre Court.

In the meantime, Andy Murray will decide whether to compete in singles at the tournament after a practice session on Monday afternoon.

The 37-year-old had an operation to take out a cyst in their spine just over a week ago.

He is getting better at playing against Kyle Edmund from Britain but still isn't sure if he's physically ready for his match against Tomas Machac from the Czech Republic on Tuesday.
