Adam Levine offers to pay funeral expenses for slain 'Voice' singer Christina Grimmie

Pop star Adam Levine has offered to pay the funeral expenses for Christina Grimmie, the former The Voice contestant gunned down last week after a Florida concert.

Levine mentored Grimmie when the singer finished third on NBC's The Voice two years ago.

Spokeswoman Carleen Donovan confirmed Monday that Levine made the offer.

Grimmie's New Jersey hometown will hold a candlelight vigil tonight to honour the 22-year-old, killed Friday night as she signed autographs after a show in Orlando.

The YouTube star lived in Evesham, N.J., a small community about 30 kilometres from Philadelphia, before moving to Los Angeles in 2012.

A motive for the shooting hasn't been determined.

Authorities say she had no apparent personal connection to the man who shot her. The gunman, identified as 27-year-old Kevin Loibl, fatally shot himself after being tackled by her brother.
