The Corrie babe, 21, was pictured just after 12.30pm today (18 March) as she and her co-star Antony Cotton travelled from Manchester to London for the showbiz bash.
Getting stuck into the onboard train refreshments, Brooke was snapped holding miniature bottles of vodka and gin while cheekily sticking her tongue out.
Antony took the picture before sharing it with his followers on Twitter. Alongside it, he commented: "So this is happening..."
Oh well, they're only little bottles...
Last night, Antony shared his excitement on the social networking site by tweeting Brooke to make sure she was all packed for their night in the capital.
"All set for London Town tomorrow and the RTS Awards. You ready @BrookeLVincent?! #SophieAndSeanOnTour," he asked, referring to their Corrie characters.
We're guessing Brooke was busy stuffing her glam frock in her case, as she didn't reply. Oops!
