Luke Littler and Eloise Milburn attended a Misfits boxing show on Saturday night, just days after the 16-year-old won the Bahrain Masters.
The teenager has become a national hero over the past few weeks, ever since storming his way to the final of the World Darts Championship.
Littler celebrates his birthday today and, with girlfriend Eloise, the couple enjoyed some time together.
The pair were snapped smiling for the cameras, with Littler also posing for a picture with ring girl Apollonia.

Littler was also filmed taking photos with KSI, with the pair spotted chatting together.
KSI asked the darts star to help him improve his performances in the sport, having seemingly been inspired by the youngster's stunning rise.
Littler and Eloise watched several big fights during the course of the night.
Elle Brook beat Andrea-June Bunker via knockout in round three of that bout.
And TikTok star Ed Matthews was beaten by Luis Pineda, who needed just two rounds to get the job done.
Eloise took to social media after the night, too.
She uploaded several pictures of herself and Littler, accompanying her post with a caption that read: "Wow, what a night."
Eloise has been supporting her boyfriend amid his sensational performances.
After Littler won in the Middle East earlier in the week, she said: "Just wow! Get in there!
"I am so proud words do not describe."
There have been fears that the gruelling schedule could be too much for Littler, especially due to his young age.
However, after beating Michael van Gerwen, he said he wants to 'play everything'.
He also added: "I'm happy to win, I played well yesterday and I've played well again tonight.
"No one probably believes me but I've not thrown a dart since the world final.
"Michael is one of the very best and I'm happy to win on my debut.

"It's been unbelievable this week and I'm happy to come out as the winner.
"I just take it game by game, if I win, I win, if I lose my next game, it is what it is.
"But I don't think about losing, I only think about winning."
Van Gerwen joked he wanted revenge on Littler for his defeat, saying: "It's never going to be a good week when I'm not winning but Luke had a fantastic performance.
"I couldn't produce what I produced in the earlier games and you get punished and that's the way sport works.
"Of course I'm disappointed but you win some, you lose some.
"I'll get him, don't worry."
