When you need a quick word of encouragement, someone to make you laugh, or someone to tell you that you're being tonta, there's no one better to turn to than your best friend.
These stars can all relate! They reveal the BEST advice their celeb BFFs ever gave them:
1. Selena Gomez & Taylor Swift
Selena Gomez admits that when she needs an uplifting word, she turns to her BFF, Taylor Swift. Swift reportedly told her to keep challenging herself to achieve great things. "She told me, 'Selena, if you're the smartest person in the room, I think you're going to be in the wrong room. She thinks I should constantly surround myself with people who are going to make me better, that are going to challenge and motivate me."
2. La La Anthony & Kim Kardashian
3. Mario Lopez & Eva Longoria
When he competed on Dancing With The Stars, Longoria commented on his manliness. "She's like, 'Don't wear anything too tight or flashy,'" Lopez revealed. "You still look kinda masculine."
4. Snooki & JWoww
These two Jersey Shore stars have shared plenty of terrible advice from their days as wild, party-all-night girls. These days, the two mamis like to swap stories about their kids. When JWoww revealed she was expecting her first child, Snooki jumped in with a set of helpful (and hilarious) advice about dealing with pregnancy.
"Sleep safe and keep hydrated, no Advil or Aleve," she texted JWoww. "No pushing on the toilet either."
Not the worst advice we've ever heard, Snooki.
5. Cameron Diaz & Drew Barrymore
These two have been best friends since they were teens - and they've seen each other through many ups-and-downs. Despite the fact that she isn't a mom herself, Cameron Diaz revealed that she helped Drew Barrymore power through her prengnacy. She bragged that she helped Barrymore get her "game face" on for pushing out the bebe.
