Caitlyn Jenner posts her first '#TBT' picture

Caitlyn Jenner is making all kinds of landmarks this week, including her first Throwback Thursday picture.

E! News reported that the 65-year-old star tweeted an adorable baby picture of her son Brandon Jenner in honor of his 34th birthday.

"Happy birthday, Brandon @sprandoni! Love you. #TBT," Jenner captioned the sweet picture.

This is one of the few tweets Jenner, who is new to Twitter, has on her Twitter. She made her Twitter on Monday after her big Vanity Fair cover reveal.

Since its creation, Jenner managed to set a world record by reaching 1 million followers in only four hours. She has been tweeting about how exciting her new life, including receiving the Arthur Ashe Courage Award at the ESPN's 2015 ESPYS.

Jenner expressed his gratitude for the award in a statement to ESPN.

"In the past few months, the overwhelming outpouring of support from all over the world for my journey has been incredible,” said Jenner. “However, being honored with this award, which is named after one of my heroes, is truly special. For the first time this July, I will be able to stand as my true self in front of my peers.”

Looks like Jenner has a lot to look forward to in July. The ESPYS will air on Wednesday, July 15 and her E! series about her transition will premiere on July 26.
