Can blondes have more fun while doing the ALS Ice Bucket Challenge? We'll see about that!
Pop superstar Britney Spears is the latest A-list star to support Lou Gehrig's disease by getting an ice-cold bucket of water dumped onto her head.
Standing near her beautiful pool, the "Circus" singer accepts sister Jamie Lynn Spears' nomination and gets a heathy dose of water.
In return, Spears nominated Adam Sandler, boyfriend David Lucado (aww!) and close friend Robin Greenhill.
Spears wasn't the only blonde to take on the challenge for ALS research.
Kate Upton participated (in a white T-shirt, we might add) and nominated close friends Leslie Mann, Cameron Diaz and Bobbi Brown.
Think of it as The Other Woman reunion.
Anna Kendrick got nominated by both Brittany Snow and Catherine Giudici-Lowe, allowing her to "double donate" to the cause Monday afternoon.
"To conserve water, I did not take a shower today," she admitted before nominating Aubrey Plaza, John Krasinski and Cat Deeley. "We can cut that part out, right?"
Last, but certainly not least, Lady Gaga got Fame Monsters cheering when she accepted the challenge in quite the memorable outfit.
Without saying a word, Gaga poured the bucket of water over her head and later nominated Adele through her Instagram caption.
The Ice Bucket Challenge has raised more than $15 million for ALS research and it shows no signs of slowing down.
This week alone, Tori Spelling, Ben Affleck, Kaley Cuoco-Sweeting, Tom Hiddleston and more stars have also stepped up to bring awareness.
