London, Sep 18 - Brazilian supermodel Gisele Bundchen and husband Tom Brady are reportedly expecting a baby boy and planning to name him Gabriel.

The 29-year-old is due to give birth to her first child with Brady in December, reports fametastic.co.uk.

'One of Gisele's five sisters is named Gabriela, and she's always thought it was a beautiful name... Gisele was brought up a Roman Catholic, and Gabriel is an archangel, a messenger from god, in the New Testament,' said a source close to her.

'She's also friends with Brazilian singer-songwriter Gabriel Guerra. They met in Rio de Janeiro last year, and he wrote the song 'Tribute to Gisele' for her. She liked it so much she put it on her website,' the source added.
