The low-key couple shunned the usual press release or Twitter announcement in favour of letting Charlotte's baby bump speak for itself at last night's Legend premiere in London's Leceister Square.
Actress Charlotte looked amazing as she displayed her blossoming baby bump in a slinky black evening gown, with cut-out back.
The couple have always kept their romance away from the spotlight. So much so, nobody even knew they had married until two months after the big day.
They began dating in 2009, after meeting on the set of Wuthering Heights, and are reported to have married in the South of France last year, in front of a small group of family and friends, including Tom's son Louis, six, from a previous relationship.
Congrats to Tom and Charlotte!
They were at the premiere of Tom's new movie Legend, in which he stars as both Kray twins, Ronnie and Reggie. The film documents their rise to gangland notoriety and their ultimate downfall.
