The star told The Ellen Show audience that the million dollar sum was her biggest ever giveaway. "I hope you continue to pay it forward and share all the good," she said, referring to the show’s recent campaign introduced as follows on the official website.

"All season long, Ellen and Cheerios want to hear stories about how you or someone you know are filling the world with good! Collectively, we're on a mission to achieve One Million Acts of Good! Join the movement, and your story could end up on the show, on Ellen's social media, or in a web video! From holding the door open for a stranger to planting a tree - no act of good is too small! Ellen and Cheerios want this to be a hub for inspiring and encouraging good!"

The TV star celebrated turning 60 on the show with celebrity pals, including Channing Tatum, Jennifer Aniston, Jamie Foxx, Jimmy Kimmel, Kevin Hart, Tom Hanks, Chance the Rapper, Michelle Obama and various others.

Last week, Irish busker Allie Sherlock appeared on The Ellen Show. The 12-year-old musician from Cork was invited to Los Angeles to meet Ryan Tedder from the pop-rock band One Republic after he saw one of her videos on Instagram.
