More and more celebrities are accepting ALS' Ice Bucket Challenge and each and every one of them has an interesting response when poured with ice cold water.

"Scandal" star and new mom Kerry Washington accepted two ice bucket challenges after her friends nominated her twice.

Pop singer Britney Spears accepted her younger sister's nomination and took on the ALS ice bucket challenge right beside a swimming pool.

Would-be dad Ashton Kutcher started off his ice bucket challenge video looking all calm and collected but the minute ice cold water poured on his skin, he could no longer stop screaming!

But the best reaction probably goes to Lady Gaga herself, who elegantly poured ice water on herself and maintained her composure all throughout.
