Then Heidi Klum's various pregnancies put her in the spotlight as the earth mother extraordinaire. Now Matthew McConaughey's gorgeous Brazilian girlfriend has raised the bar for anyone aspiring to be the poster girl for maternity. Baring her growing bump in a two-piece on the beach in Malibu, Camila Alves, a model, was a vision of expectant motherhood as she spent a day lounging by the shoreline with the Sahara actor and their little boy. Amazingly, their son Levi only turned one in July, making it all the more remarkable that 27–year-old is on such radiant form. The way she's taken this latest pregnancy in her stride will have earned her the admiration of her Hollywood love. When he announced the happy news on his website earlier this year Matthew was clearly delighted. "Levi is going to be a big brother…, "he told fans. "Yeah, we pulled off the greatest miracle in the world one more time, Camila and I are expecting our second child, bringing more life into the world, making more to live for."
