Caitlyn Jenner posted a message of empowerment on her Twitter account, which has attracted nearly 2.5 million followers since it went live last week.

"Learn from those who have walked the path before you. #TransIsBeautiful #LivingOurTruth #JustTheBeginning," Jenner tweeted alongside an outdoor photo of herself with five other women.

Jenner and her companions, who are not identified, are seen from behind and all have their arms around each other's backs as they look out at mountains and trees beyond a luxurious swimming pool on a bright, sunny day. Jenner is wearing skinny jeans, a floral peasant top and sandals in the snapshot.

The 65-year-old Olympian and reality TV star, formerly known as Bruce Jenner, introduced the world to her female persona with a glamorous photo on the cover of this month's issue of Vanity Fair.

Her new docu-series I Am Cait is scheduled to premiere next month.
