Suits actor sings for guests at hotel bar during Meghan Markle's wedding reception.

He sent viewers into meltdown after he pulled an 'unimpressed' facial expression during the Royal Wedding between Prince Harry and Meghan Markle.

But it is unclear whether Rick Hoffman attended the glitzy reception, as he was captured singing to an array of guests at a local hotel on the night of the second set of celebrations on Saturday.

Posted onto make-up artist Rachel Renna's Instagram account, the Suits star, 47, appeared giddy as he belted out a series of Michael Jackson's chart-topping hits in front of his amused pals.

Meghan's co-star opted for casual attire as he swayed behind a pianist, while delivering a funny rendition of Billie Jean. 

Rachel - who recorded the clip - was in high spirits as she said: 'He's getting into tune, he's warming up, I like it!'


MailOnline has contacted Rick's representatives for comment.

Meghan and Harry's evening guests are known to have included Serena Williams, Priyanka Chopra and her good friend Jessica Mulroney.

Celebrities arrived in their droves at Frogmore House for a wedding party that included jokes by James Corden and music by Sir Elton John.
