Happy birthday, Laura Robson! The rising tennis star, who won the Wimbledon juniors title in 2008, is no longer a teen. Ranked No. 48 in the world, the 20-year-old lefty was named the WTA Newcomer of the Year in 2012 and won the silver medal in mixed doubles with Andy Murray at the 2012 London Olympics. Robson became the first British woman since 1998 to reach the fourth round of a major at the 2012 US Open and the first British woman to reach a WTA main-tour final since 1990 at the 2012 Guangzhou Women’s Open. Robson, who reached a career-high ranking of 27th last July, has had a disappointing start to her 2014 with a first-round loss to Kirsten Flipkens at the Australian Open last week. And, she'll have to understand if best pal, 19-year-old Canadian Eugenie Bouchard, can't make it to her party. Bouchard, the 2013 WTA Newcomer of the Year and the 2012 Wimbledon juniors champ, is in the Australian Open semifinals after knocking off Ana Ivanovic on Tuesday.
