Youre in their heart, Sir Rod Stewart.

The 74-year-old British rocker turned a wedding that had been in tatters into the nuptials of a lifetime on Wednesday, serenading the couple with Have I Told You Lately at their Las Vegas ceremony.

Days before it was looking grim for Sharon Cook, Andrew Aitchison and their 14 guests, who were stuck in Liverpool, England , after their flight to Vegas was canceled when travel group Thomas Cook collapsed.

But then Delta Air Lines and Caesars Palace hotel stepped in to help with travel arrangements and Stewart gave the pair the ultimate upgrade with his surprise gig.
