Bellingham was on hand to score the opener for Los Blancos in the 36th minute against Girona.
Madrid's Brahim Diaz drove into the box before he looked to cut the ball back to the many teammates waiting patiently near the goal.
Girona managed to block the initial cutback but it soon fell to Bellingham, who smashed the loose ball into the net.
The England international then made his way over to the corner flag where he showed off a new celebration.
Bellingham gripped the corner flag with his left hand, bowed his head and lifted up his right pinkie finger.

Along with his goal putting Madrid ahead over Girona, it proved to be a historic strike for Bellingham.
The 21-year-old's goal meant he had scored in five consecutive LaLiga matches - the first player to do so this season.
Bellingham's sensational run of form also marked the first time he'd scored in five-straight league matches since he joined Madrid from Borussia Dortmund for a cool £88.5million in 2023.
The midfielder then turned provider for Madrid's second, as he slipped teenage talent Arda Guler through with a delightful through ball and the Turkish international did the rest.

Unfortunately for Bellingham, his outing came to an end in the 61st minute when he was substituted off for Dani Ceballos.
Bellingham did not appear to be moving freely, prompting Madrid boss Carlo Ancelotti to avoid taking any risks with his superstar.
Superstar striker Kylian Mbappe added a third for Madrid in the 62nd minute to round off a comfortable win.
Bellingham's outstanding run of goals represents a complete contrast to how he began the season for Madrid.
The midfielder failed to score in his first seven LaLiga fixtures before he finally registered his first goal of the domestic campaign against Osasuna on November 9.
It brought an end to a goal drought that had lasted 12 games and 179 days.
Goals against Leganes, Getafe and Athletic have followed, although Bellingham is yet to score in the Champions League this term.
Luckily for the midfielder, he has a chance on Tuesday to end the wait as Los Blancos travel to Europa League champions Atalanta.
Speaking in the midst of Bellingham's goal drought, Ancelotti revealed he was 'very satisfied' with the England international's work, even though it wasn't translating to goals.
"He works a lot, he's always present, he competes, he fights, he sacrifices himself," Ancelotti said in October.
"It's true he hasn't scored the goals he scored last year, but the surprise isn't this year, the surprise was last year, when he scored lots of goals which nobody expected and helped us a lot.
"The problem this year isn't that we're lacking Bellingham's goals.
