Aww!

The world is fascinated with watching Bruce Jenner's transition into becoming a woman -- and we can't blame them -- so are we. Last night, the new special, Keeping Up With the Kardashians: About Bruce, debuted on E! and the show's viewers weren't just gossip-hungry audiences or random fans supporting the Olympian. Bruce's own stepdaughters were among the millions watching the special. Both Kim Kardashan and Khloe live tweeted their support and their experience watching last night's emotional episode.

Last night, Kim wrote, "Seeing @KendallJenner & @KylieJenner cry makes me cry watching this #KUTWK #AboutBruce."

Khloe, whom Bruce said has had the hardest time accepting his transition, wrote that watching the episode was very difficult, "Such an emotional KUWTK special tonight. This was filmed incredibly raw and rough. Please take in this is hard for us all to live on TV."

After the episode, Khloe added, "I hope you guys enjoyed tonight's part1 special of About Bruce. And Im anxious for you guys to see part 2 tomorrow 💋 so proud of Bruiser."

We are glad to see that the gals are on board with Bruce during the new (and very public) chapter of his life.
