The model, who is pregnant with her first child and also expecting via a surrogate, looked radiant as she attended the Serpentine Gallery Summer Party at Kensington Gardens, with boyfriend Ty Comfort.
Caprice wore a peach high-neck textured shift dress with green bug designs embellished over her bump. The 41-year-old teamed her quirky dress with gold heels and a small clutch bag, meanwhile Ty looked smart in a grey suit.
The couple were all smiles and held hands as they left the annual event, which was graced by an international A-list of celebrities including Naomi Campbell, Kate Moss and Sarah Jessica Parker.
Caprice, who announced her pregnancy in May, had secured a surrogate before finding out she was pregnant naturally.
Last week, the American-born businesswoman spoke openly about her hopes to start family on ITV's This Morning, saying it was a "feeling of happiness". She added: "I've waited 41 years for this, I can't wait!"
