Lady Gaga rocketed past the 20 million Twitter followers mark yesterday. She’s the first person to ever reach that milestone.

And the attention she has received for reaching the 20 million mark has only added to her following. Just one day later, she has added another 73,000+. Lady Gaga has been the top celebrity on Twitter for quite some time now. She has been on the top of the leader board with the most Twitter followers since August of 2010, when she usurped Britney Spears from the lead. In June of last year we reported that she had reached the 11 million follower mark.

Justin Bieber is not far behind Lady Gaga in the Twitter follower count, with 18 million. Bieber is followed up by Katy Perry with almost 16 million, and Shakira and Rihanna, which each have close to 14.5 million (Shakira’s slightly ahead).

In addition to her Twitter following, Lady Gaga has nearly 49 million Facebook ‘Likes’ and is in about 830,000 Google+ circles.
