The first official promo for Caitlyn Jenner’s new docuseries I Am Cait has received more than 4.5 million views across E!’s digital and social platforms in the first 24 hours after its debut.

That combined with the news of Kim Kardashian’s pregnancy led to E! Online’s biggest non-awards day of 2015 with 5.2M uniques, E! said today.

The promo was released just days after Vanity Fair blasted out to media the cover of its June issue featuring Caitlyn Jenner, formerly Bruce Jenner, on the cover, in an ivory satin teddy.

I Am Cait explores Jenner living as a transgender woman and seeking her “new normal.” It also will look at what the transformation means for the people around her. The eight-episode, hourlong show premieres at 9 PM July 26 on E!
