We're absolutely hooked on this year's Britain's Got Talent live shows. Partly because the acts seem to getting better and better (we're still SHOOK over incredible magician Marc Spelmann), and partly because Dec Donnelly is doing an amazing job of hosting the shows solo.
Dec took on job of presenting alone after Ant McPartlin made the decision to cancel all his TV commitments following his arrest for drink driving in March and a second stint in rehab.
Fans have been quick to congratulate Dec for his solo efforts, and were left chuckling when the presenter jokingly referenced being separated from his TV partner on last night's live show.
Speaking to the camera as he introduced jazz singers Dennis DeMillie and Marvin Muoneke, Dec said: "We start with two men who are absolutely inseparable.
"They're a double act everyone loved in the auditions and now they're back together for semi-final week. Must be nice."
Reacting to the joke, fans took to social media to praise Dec again.
One wrote: "When Dec makes jokes about Ants absence, it makes my heart swell! He’s acknowledging that he misses him and he’s making a joke before anyone else can #BGT 😭"
Dec's also spoken out on Twitter about the support he's received from fans, thanking them for all their kind words.
