From Celine Dion's tear-jerking rendition of 'My Heart Will Go On' to an accidental F-bomb.

The pair first met and began dating in 2013.

Many people on social media were quick to point out that the 44-year-old TV host himself has been accused of sexual misconduct.

It was a weird, dull and seemingly lonely Oscar night for the normally busy E! red-carpet maven Ryan Seacrest, who's facing sexual abuse allegations.

"This person who has accused me of horrible things offered, on multiple occasions, to withdraw her claims if I paid her millions of dollars. I refused," Ryan Seacrest said.

Ryan Seacrest was the first to make the sexual misconduct accusations public when he issued a denial last November.

"I’m proud of my workplace reputation, and believe my track record will speak for itself. I’m an advocate for women," Ryan Seacrest said in a statement.

Combined, the world’s 10 highest-paid TV show hosts earned US$462.5 million between June 1, 2016 and June 1, 2017.

Luke Bryan, Lionel Richie and Katy Perry will make their on-camera debut next week when they appear together for the first time on 'Good Morning America.'

Ryan Seacrest took to Twitter to confirm the news, writing that he’s “so excited to join this show!!"
