Call me baby! Pregnant Charlotte Riley reveals her bump as she and Tom Hardy take to the phones for charity

They're both heavy-hitters in the acting world, but Charlotte Riley and Tom Hardy were taking time out of their schedules for charity on Friday.

Taking to the phones on BGC brokers out on the trading floor, the acting duo took part in the annual fundraiser - in particular Bowel Cancer UK, which they wore like a badge on their clothes.

The cute twosome, who are expecting their first child together before the year is out, put on a playful display, mucking about on the lines as they lent their star power to 20 very good causes.

Charlotte only dropped the very public bombshell that she was expecting her first child last week when she accompanied Hollywood star Tom to his London premiere of Legend.

But it seems she's kept the secret well because she was looking far along on Friday as she dressed her baby bump in a sophisticated grey dress.

The pretty Peaky Blinders star looked polished with her tresses in a short fringed bob and cute bow pumps on her feet.

Tom's image was a far cry from last week's sharp-suited and suave image and he wore a blue cap and scruffy jeans.

But, with his softer side on show for once, the Mad Max actor was dressed in a T-shirt with the name of charity, for which they were both named patrons in 2012.

The charity's Chief Executive Deborah Alsina noted that it had been 'Tom Hardy mania' on the trading floor that day as fans of the actor tried to catch a glimpse of the high profile star on his visit.

They joined radio host Dermot O'Leary in their support for the UK charity, with representatives taking to the official Twitter account to say they were 'so grateful for the support'.

Tom is due to appear on Alan Carr's Chatty Man on Friday night to talk about his new Kray twins biopic.

The funny man will also be welcoming This Is England actors Stephen Graham, Vicky McClure and Thomas Turgoose and American songstress Demi Lovato.
