Rihanna had the “best day” of her life when Germany won the 2014 World Cup.

The Barbadian songstress has been tweeting constantly as teams around the globe faced off at Maracanã in Rio de Janeiro, Brazil for the championship title.

And RiRi made her allegiances clear as Germany’s Mario Gotze scored the team’s first and final goal against Argentina on Sunday for a 1-0 win.

“Best day of my life,” she tweeted alongside a photo of players celebrating on the field.

“Congrats to my German boyz! This was the most epic experience of my entire life! You guys made me so proud to be here,” she wrote, adding another photo of herself celebrating in the stands, adding: “Hello from FIFA Brazil.”

Stars including Sarah Hyland and Gisele Bündchen were cheering in the stands, as was David Beckham, who brought sons Brooklyn, 15, Romeo, 11, and Cruz, nine, to the match.

Many others meanwhile logged onto social media from around the world.

"The more they play, the more I eat #worldcup," Ryan Seacrest tweeted as the game went into overtime.

“This was 1 of my most exciting #WorldCup I have seen in my life.. My love to all the teams for leaving it all on the field. #WorldCup2014,” Wilmer Valderrama wrote.

“#Germany yes yes yes!!! #WorldCup,” Candice Swanepoel added.

Kellan Lutz was meanwhile soaking up the sights from Rio when he wasn’t posing with fans.

“I’ve been trying to come to Brazil for years now and finally the stars lined up and it just so happened to be for the FIFA World Cup! Killing two Bucket list birds with one stone! #Blessed #FIFAWorldCup2014 #Brazil,” he tweeted.

The actor later added a shot of himself looking over the horizon.

“Soooo, I'll be here..” he wrote.
