SIAN: FUN IN THE SUN

- 

IT might be June but Mariah Carey could yet sprinkle some Christmas cheer on London.

The iconic diva tops the bill at the Capital Summertime Ball on Sunday and host Siän Welby admits they will be asking her to get a bit festive despite the forecasted heatwave.

Siän told me: “We always get Mariah out of Christmas and defrost her, and this is what we're trying to do at the weekend.

“We really want her to do the Christmas song at the Ball, even in 25 degrees because we think it'll be hilarious.”

Mariah has reputation for being the ultimate diva but Sian is ready for anything: “I’ve not had any demands yet. They say no news is good news!
