Usher to wed on Saturday?

R&B superstar Usher is planning a secret weekend wedding, according to US reports.

The Yeah! hitmaker is hoping to exchange vows with pregnant fiancee Tameka Foster at music producer Antonio 'L.A.' Reid's Hamptons estate in New York on Saturday, according to OK! magazine.

A source tells the publication the couple is rushing wedding plans because they want to be man and wife before Foster gives birth.

The couple announced they were expecting a child together last month.
