Kelly Clarkson may marry this weekend

Kelly Clarkson has sparked speculation that she could marry music manager Brandon Blackstock this weekend.

The rumours emerges after the 31-year-old singer and her fiance filed for a marriage license in the town of Sumner Country, just north of Nashville, and now have 30 days to get hitched, Contactmusic reported.

According to People magazine, the couple could marry as soon as the weekend.

Contrary to her envision of a big wedding, the couple may have an intimate ceremony with just Savannah and Seth, Blackstock's two children, on the guest list.
