Adriana Lima revealed this morning that she has finally given birth to a daughter called Sienna; her second child with her NBA player husband Marko Jaric. The Victoria's Secret model posted a quick announcement on Twitter this morning which read: 'Marko and I are overjoyed to welcome Sienna into our family and Valentina is looking forward to becoming a big sister!' Valentina is their first child who was on November 19th 2009. Now we just need to wait for some Adriana Lima baby pictures!

The Brazilian beauty posed for the Vanity Fair 2012 Pirelli calendar whilst she was pregnant with Sienna, making her the first model with a bump to be pictured in the famous Pirelli shots. They may end up having to include more mothers-to-be in their calendar, as it seems Lima is not the only model to be starting or expanding on their family. 26-year-old American VS model Lily Aldridge gave birth to her first child Dixie Pearl in June with her Kings Of Leon honey Caleb Followill and Alessandra Ambrosio had her second child Noah Phoenix back in May this year.

We're looking forward to seeing Lima hit the next Victoria's Secret catwalk show in November; new babies are no excuse as was demonstrated by Ambrosio in 2008 when she hit the runway a little over two months following the birth of her daughter Anja Louise and Heidi Klum appeared at work only 5 weeks after bringing her fourth child into the world.
