Happy Birthday to the biggest pop goddess of all time.

How Lady Gaga Got Her Groove Back

Lady Gaga turned 29-years-old on Saturday and she has had a heck of a year. This includes being cast on American Horror Story, singing a breathtaking performance at the Oscars and making plans to tie the knot with boyfriend Taylor Kinney.

While Gaga has had a pretty epic year, she is also known for having a memorable past when it comes to the music industry. Starting off as a pop star, she set herself aside from the typical style and became something far more iconic. She's taken on a variety of bizarre styles when she attended award ceremonies, including a dress made of meat and another with life-size bubbles.
