Gisele Bundchen's dog has died.

The devastated supermodel took to her Facebook page to share the sad news that her beloved Yorkie Vida, who was even part of the wedding party when she married Tom Brady, has died.

She wrote: ''My best friend, she will always live on in my heart. Let's never take for granted the unconditional love that our animals show us every single day.''

Gisele is currently pregnant with her second child with husband Tom and it was recently revealed she would like to have a sister for her two-year-old son Ben, but will not find out the sex in a scan because she wants to keep it a surprise.

A source said: ''She's hoping it's a girl - she loves little girls. But she wants to be surprised like when she had her first baby Ben.''

Gisele is dealing well with her pregnancy, but is keeping active and healthy so she can return to work.

The source added: ''She's still exercising and very active. She'll be back on the runway in no time.''
