‘Newly Engaged’ Jack Whitehall hits the phones with Rachel Riley, Martin Freeman and Jerry Hall at the 32nd Annual ICAP Charity Day

Jack Whitehall was among stars hitting the phones at the annual ICAP Charity Day on Wednesday afternoon as he mediates alongside Rachel Riley and Martin Freeman.

The ‘newly engaged’ comedian, 36, looked like he meant business as he juggled two phones at the trading firm’s London headquarters for the annual charity event.

ICAP Charity Day raises money for charities around the globe, with the company and its brokers giving away 100 percent of a day’s turnover.

Jessie Ware helped make deals with customers and wore a light green t-shirt and black jeans while holding two phones to her ears.

Staff donned their best attire for the occasion and Jessie was joined on the phones by two staff dressed as McDonald’s mascot Ronald – as well as another trader in full Greek god regalia.

Meanwhile, Irish presenter Laura, 39, looked suitably festive in a bright red sweat and appeared office-ready as she made animated trades across the floor.

Beaming from ear to ear, Laura showed off her bright red lipstick as she got into the spirit of the high-pressure environment.

Also making an appearance was the former England captain, 44, who made some calls alongside a pair of traders channeling their best 70s disco divas.

He was also seen beaming with a group of shoppers dressed in snowsuits – with one in particular reminiscent of George Michael’s classic Last Christmas music video ensemble.

John kept his outfit low-key as he sported a navy blue sweater, as well as wearing a ribbon representing the Rays of Sunshine Children’s Charity.

ICAP Charity Day has had a significant impact since it started in 1993, raising more than £165 million.

The funds raised over the years have been donated to more than 3,000 charities around the world.

Charity Day is shaping up to be quite a star-studded affair, with Joan Collins, Alex Scott and Billie Piper looking office-ready as they attended last year.

Actress Joan, 91, cut a glamorous figure in a sparkling silver blouse, which she teamed with black trousers.

The former Dynasty star also wore a pair of eye-catching red leather baubles along with a silver cross necklace.

Alex was all smiles as she posed with actress Billie Piper, 41, who matched the former England footballer in a similar black blazer with glittery black details.

The couple got involved with the team and posed with brokers who embraced the festive cheer by dressing up as an elf and Oompa Loompa.
