Luke Littler poses with Apollonia Llewellyn as he watches Misfits boxing with girlfriend Eloise on eve of 17th birthday

DARTS sensation Luke Littler enjoyed a birthday night out as he posed with ring girl Apollonia Llewellyn and YouTube star KSI at a Misfits boxing show on Saturday night.

Littler – who turns 17 on Sunday – claimed his first senior PDC title on Friday evening, beating three-time world champion Michael van Gerwen in the final.

He also made history in his quarter-final after becoming the youngest player to hit a nine-darter in a senior PDC darts event.

Less than 24 hours later he was back in England attending a boxing show with girlfriend Eloise Milburn, 21.

Littler, whose meteoric rise came as a result of his run to the World Darts Championship final earlier this month, was pictured ringside at the Misfits event in Leeds with his partner.

Model turned ring girl Apollonia got herself a snap with the darts star as she held her nephew up in the middle of the picture.

And she added the caption: “One happy nephew.”

Littler was then filmed taking photos with KSI as the pair exchanged a few words.

KSI could be seen asking Littler to show him how to improve his darts game.

Social media users reacted in their droves after seeing Littler and KSI together.

One person said: “He’s probably buzzing inside [Littler]. I know everyone says it but its easy to forget hes still a kid inside and is probably starstruck meeting one of his idols .”

Another added: “Luke Littler in a Sidemen video .”

A third replied: “He should be signed to Misfits.”

While a fourth responded: “My goats.”
