Irish singer Sinead O'connor hates Andie MacDowell's TV hair commercials so much she has warned the actress she'll shave off her locks should they ever meet.

Outspoken O'Connor, who infamously shaved her head when a music industry boss advised her to never cut her long hair, finds the FOUR WEDDINGS AND A FUNERAL star's adverts irritate her a great deal.

O'Connor says, "I absolutely hate those hair commercials she's done. They drive me crazy. She looks so prim and proper.

"If I ever get the opportunity to meet her, I'm going to shave all her hair off."
