Atomic Kitten singer Natasha dazzled as she dressed her bump in a slinky black dress with embellishments, which she teamed with black sandals and a metallic clutch bag.
Meanwhile, 5ive singer Ritchie looked smart in a black suit and tie, as he arrived with Natasha at the London Cabaret Club's spring VIP launch.
The couple, who found love after reconnecting on the first series of ITV reality show The Big Reunion last year, looked loved-up as they posed for photos on the red carpet.
'Whole Again' singer Natasha announced her pregnancy last month, saying she was "thrilled" to be expecting a child with Ritchie.
Natasha is already mum to sons Josh, 11, Harry, eight, and Alfie, three, from previous relationships, but this will be her first child with Ritchie.
Last week, 31-year-old Natasha shared a a scan picture of her unborn baby on Twitter. She said: "Our little bundle of joy. Halfway there now, so excited to meet my baby x."
While they're planning to keep the sex of their baby a surprise, the loved-up couple couldn't hide their excitement this week. Natasha revealed (7 May): "Had a nice evening modelling my rather big bump for @RitchieNeville whilst he took some more piccy's to document our journey 4 the baby."
