Ryan Seacrest and Julianne Hough were on there way to London for Valentine's Day weekend when their plane made an emergency landing in Vegas. A British Airways spokesperson says, ''Safety is always our top priority and as a precaution, the Captain decided to divert our Los Angeles to London service into Las Vegas, following a suspected technical problem. Our pilots used their training and experience throughout and the flight landed normally at Las Vegas. We provided hotels for the customers and we will be rebooking.''
