Hollywood and the Internet collided at the 5th Annual Streamy Awards on Thursday night, but that's actually been happening a lot lately for YouTube stars Mamrie Hart and Grace Helbig.

Over the last few weeks, the comedians and best friends have shared snapshots on Instagram of their hangouts with big names, including Taylor Swift and Reese Witherspoon. Of course, we had to ask about the ladies' day with the Oscar winner, who called the YouTubers "an inspiration" in her own Instagram post.

"Hashtag secret project," Hart teased, possibly in reference to a collaboration. After all, Witherspoon did just get into the digital space herself with her lifestyle site, Draper James.

Helbig was a little more forthcoming with the information, calling her and Hart's date with Witherspoon "bizarre."

"Reese, turns out, is a huge Internet fan," Helbig said with a smile, "and just genuinely curious about the space. And, so, I never thought that I would use Reese Witherspoon's name and the term 'genuinely curious' in a sentence together. Yeah... it was a very bizarre... sitting down and having lunch with Reese Witherspoon? It was very cool."

We'll have to wait and see if a "secret project" between Hart, Helbig and Witherspoon ever actually comes to fruition, but Hart did promise some big news coming soon from "The Holy Trinity," aka Hart, Helbig and their fellow YouTuber, Hannah Hart. 

"We have some things that we'll be announcing soon," Hart said. "It's super exciting! ... I'm a constant tease." 

Well, you can at least get more of Helbig right now. Check out the video below to see ET's chat with the comedian before taking on hosting duties at the Streamys alongside Tyler Oakley.
