Louis Tomlinson And The Weeknd Perform On The X Factor UK: Watch

Louis Tomlinson put on a brave face to perform "Just Hold On" on The X Factor UK Saturday night.

Just days after losing his mom Johannah to leukemia, Louis Tomlinson took the stage to sing his new Steve Aoki-produced song "Just Hold On," which he dedicated to his mother.

If you're shocked at how fast the former One Directioner jumped back into the spotlight following the loss, it's because this moment was one of her dying wishes.

"Louis will go ahead with his debut solo performance at the X Factor final tomorrow night in tribute to his late mother. The performance was long-planned and it was one of Johannah’s dying wishes for Louis to take the stage. As a result, he will go ahead with what she wanted."

At the time of posting, hashtag #ProudOfLouis was the number one world-wide Trending Topic on Twitter.
