Charlotte Casiraghi of Monaco was spotted at the Pro-Am equestrian competition last night sporting her large baby bump.
The 31-year-old was at the event with her mother Princess Caroline of Hanover to give prizes to the team Federation Öquestre de la Principaute de Monaco with Mona Ferry and Christian Rhomberg, the winners of the Longines Pro-Am competition.
Casiraghi, who is married to 36-year-old film producer Dimitri Rassam, wore a collared black maternity dress as she beamed to cameras at the lavish event in Monaco.
She had managed to keep the news secret when rumours circulated in March this year about her pregnancy, when she attended the annual Rose Ball in Monaco.
Casiraghi wore an oversized fur coat which concealed her figure but she did make sure she was wearing a diamond ring on her left hand, which sparked rumours about her relationship with Rassam.
The couple are expecting their first child together later this year, but both are already parents from previous relationships.
