The England and Los Blancos superstar made a return to his club's starting XI following a shoulder injury that kept him out of action for Real Madrid's last outing before the international break as well as England's Euro 2024 qualifiers against Malta and North Macedonia.
But it was like he never left as he carried on his sensational output by scoring and also supplying the assist for Rodrygo, who put Real Madrid ahead at Cadiz on Sunday.
Bellingham put Carlo Ancelotti's men out of sight on 74 minutes as he confidently drilled the ball home with his left foot to seal a 3-0 win.
The 20-year-old provided the assist for Rodrygo's opener, but in truth, the goal was all about the Brazilian forward.
After receiving the ball from Bellingham on the left, Rodrygo cut inside and went past four Cadiz players - a move which included a nutmeg on Alex Fernandez - before brilliantly firing into the top right-hand corner of the net.

Bellingham didn't play much of a role in Real Madrid's second of the evening, but it was more outstanding work by Rodrygo.
The 22-year-old received the ball from Luka Modric midway through Cadiz's half before working some space for himself with two dummy shots before firing the ball through Jeremias Ledesma to make it 2-0 on 64 minutes.
But the season has been all about Bellingham who now has 18 goal contributions in 15 appearances for the Spanish giants (14 goals and four assists).
He's taken to life at the Bernabeu like a duck to water and will be key in their pursuit of the LaLiga title as well as the Champions League.
