Caitlyn Jenner breaks Barack Obama Twitter record for fastest to one million followers

Step aside Barack Obama, Caitlyn Jenner is the new queen of Twitter.

In just about four hours, Jenner has amassed one million followers -- one hour faster than President Obama's record in May when he established the @POTUS Twitter account.

Jenner's first written tweet has been retweeted more than 180,000 times.

Stars such as Ellen DeGeneres, Emma Roberts, Emmy Rossum, Sam Smith and Grant Gustin tweeted their support to Jenner, possibly helping her to accumulate followers so quickly.

Obama has yet to deliver his concession tweet.

The creation of Jenner's Twitter account, @Caitlyn_Jenner, was just part of a huge day for the former Olympian and reality star that introduced the world to Bruce Jenner's new female persona after completing a process of gender transition.

Vanity Fair led the way when it unveiled the first photos of Jenner as a woman on Monday morning. Jenner serves as the cover story for the magazine's July issue.

Later in the day, ESPN announced that it will be honoring Jenner with its Arthur Ashe Award for Courage at the ceremony in July, which will also broadcast live on ABC. Currently, the appearance will be Jenner's first public appearance since completing her transition.

Jenner plans to share more of her new life in a docu-series for the E! Entertainment network premiering in July 26.
