The little brother of Irish jockey David Mullins shed teas of joy after watching his sibling win the Aintree Grand National.
The Goresbridge jockey rode 33/1 outsider Rule The World to victory yesterday, making the gelding the first Irish owned and trained horse to win the prestigious race in six years.
It's been a rocky road to victory - the horse has suffered his fair share of problems in recent years, breaking his pelvis on two occasions.
When David came into winners enclosure to celebrate with his family, his younger brother Charlie couldn't just hold it in anymore.
Little Charlie Mullins wasn't the only one feeling emotional after Saturday's momentous triumph - trainer Mouse Morris was also reduced to tears in the immediate aftermath of the victory.
It has been a difficult time for Co Tipperary handler, who endured the tragic death of his son, Christopher, last summer.
He admitted yesterday that he could not believe what he was seeing.
"Watching the race I thought we were going to be third and I was going to be very happy with that. It would have been a fantastic run," he said.
"From where I was watching it, I didn't really believe it until he passed the winning post.
"He's a horse I always thought an awful lot of until he had his injuries. He's a typical National horse - he's a big horse that jumps well and has a bit of class.
"The funny thing is he's actually a good ground horse. Because of his injuries, his rear end isn't as strong as it should be muscle-wise and I think the better the ground the better he is."
Owner Michael O'Leary hinted after the race Rule The World could be retired, but Morris is keen to enjoy the moment before considering future plans.
He said: "I'd say it's very unlikely he'll run again this year, anyway.
"We'll let the smoke clear and dust settle and we'll see where we are after that.
"The horse won't be abused, that is for sure."
The Ryanair boss and his brother Eddie who run Gigginstown stud are set lead the gelding through Mullingar today.
