Heading into the capital's West End, the couple attended the launch night of new play Photograph 51 at the Noël Coward theatre to see Hollywood A-lister Nicole Kidman in action on stage.
And on arrival to the show, Tom and Giovanna were all smiles, leaving their one-year-old son Buzz to be looked after home, to enjoy some one-on-one time together.
Cuddling up for the camera before taking their seats, Giovanna kept her baby bump hidden under a loose-fitted shirt dress. Tom, meanwhile, looked dapper in a jeans and blazer combo.
Inside the theatre, the pair joined the likes of Tom Daley, Britain's Got Talent judge David Walliams and comedian Dawn French.
Following the show, both Tom and Giovanna were quick to tweet about the play, crediting Nicole and the rest of the cast for their performances.
While McBusted's Tom said Photograph 51 was "awesome". Giovanna told fans: "Date night with the hubby. Went to see Photograph 51 at The Noel Coward theatre. So beautiful."
Their evening out at the theatre comes after Tom and Giovanna joined her brother and former TOWIE star Mario Falcone in Centre Parcs over the weekend.
The Falcone family had got together to celebrate the birthday of Giovanna and Mario's dad, and while there, Mario kept fans updated with plenty of family snaps - including a super cute photo of himself and his nephew Buzz.
Taking his uncle duties in his stride, following his short break away, Mario gushed he couldn't wait for his sisters to give him more nieces and nephews in the future.
Luckily for him, he already has another on the way as Giovanna and Tom are expecting their second child together. The couple announced their exciting news at the beginning of September, sharing the *cutest* video to do so.
As well as their adorable clip, Giovanna addressed her baby news by telling fans: "Super happy to be sharing our news with you all today. Can't wait to meet Buzz's little brother or sister. Thanks for all the love. xxx."
Tom added: "Happy and excited don't quite cover it."
