Julia Roberts' ex-husband Lyle Lovett is planning to walk down the aisle for a second time.

The 45-year-old country singer, who was married to OSCAR-winner Roberts for two years from 1993, has become engaged to his former personal assistant APRIL KIMBLE, 28.

The couple, who have been dating for about five years, have yet to set a wedding date.

It will be the first marriage for Kimble.
