Gisele Bündchen is pregnant with her second child, according to reports.

A source has told Us magazine that the Brazilian supermodel and her American footballer hubby Tom Brady are expecting their second child at the end of the year.

"Yes, she is pregnant," the source told the magazine. "They are really happy."

Despite reportedly being three months pregnant, the 31-year-old stunner showed no signs of a mini bump as she arrived at Rio de Janeiro airport to catch a flight yesterday.

If the rumours are true, she'll no doubt be hoping this pregnancy and birth is as easy as her first. She told a Brazilian TV channel that her first birth 'didn't hurt in the slightest'.

Yeah, right.
