Sometimes, we get lucky enough in life to meet a kindred spirit who just *gets* us. Studies have shown that having a best friend in your teenage years could sow benefits you can reap for years. After all, your BFFs聽lend you a shoulder to cry on when you鈥檙e down and聽cheer for your accomplishments. That鈥檚 why it warms our hearts when we see Hollywood stars celebrating and supporting their BFFs. Here are five funny, sweet, and downright tear-jerking examples of celebrity acts of friendship.

BEVERLY HILLS, CA - JANUARY 07: Actor Busy Philipps (L) and Michelle Williams attend the 2018 InStyle and Warner Bros. 75th Annual Golden Globe Awards Post-Party at The Beverly Hilton Hotel on January 7, 2018 in Beverly Hills, California. (Photo by Donato Sardella/Getty Images for InStyle )

1. When Busy Phillips Flew to Be with Michelle Williams on the 10th Anniversary of Heath Ledger鈥檚 Passing:聽They might have met on the set of聽Dawson鈥檚 Creek when they were newcomers in Hollywood, but their friendship has stood the test of time. They鈥檝e seen highs (like when the pair were attending Paris Fashion Week last year, they got a little tipsy, and Williams entrusted her friend with dyeing her platinum pixie millennial pink) and lows.

Williams鈥 partner and father of her 12-year-old daughter Matilda, Heath Ledger, died on January 22, 2008. Phillips, knowing that the 10th anniversary of his death would be hard for her bestie, got on a flight, and flew to her friend. She snapped a photo with her friend with the words 鈥淚t鈥檚 ok.鈥

2. When Jennifer Lawrence Walked Out of a Glam Sesh to Hang With Emma Stone:聽In a friendship match made in heaven, two of Hollywood鈥檚 funniest leading ladies happen to also be besties. Lawrence doesn鈥檛 seem to be the least bothered that her pal edged her out of the position of being the highest paid actress of 2017. In fact, the pair had plans to attend the 2018 Golden Globe Awards afterparties together when Stone changed her mind about going out. Lawrence, who was already in the makeup chair for her after hours look, promptly walked out and left with HALF her glam on.

She hilariously details her experience for the world on聽Facebook. When Stone asks her what happened,聽 Lawrence replies,鈥漌ell, you had told me that you wanted me to be your date to the afterparties so I, you know, got us some tickets to some afterparties.鈥

鈥淚 booked a car and I was halfway through glam,鈥 she continued, revealing her whole face, 鈥淲hen you told me that you didn鈥檛 want to go. You just wanted to come over to my house. So, I sent my hair and makeup team home. And now this is what I look like.鈥

3. When Janet Jackson Surprised Missy Elliott at an Awards Show:聽The pair has collaborated on songs like 鈥淪on of a Gun鈥 and 鈥淏urnitup,鈥 but their friendship goes far beyond the recording studio. Elliott was honored with the Visionary Award at Essence鈥檚 9th Annual Black Women in Music event last week, and while the rapper/producer knew the recognition was coming, she didn鈥檛 know her best friend Janet Jackson would be the one presenting it.

And Jackson prepared a personal speech for the occasion. 鈥淚 am so grateful for Missy鈥檚 beautiful soul. I am grateful for her creativity, her energy, grateful for her soaring inspiration. I鈥檓 grateful for how she stood toe-to-toe with the guys, showing them that a woman can do it all, take charge, lead the way, innovate, and create without fear,鈥 she said of her pal of over 17 years. 鈥淕rateful for how she鈥檚 cleared the way, the path, for new generations of young talent to follow. And I am so very grateful for聽her loyal friendship聽that has meant more to me than she could ever know.鈥 Elliott says she was brought to tears over Jackson鈥檚 speech. D鈥檃ww.

4. When Jennifer Aniston and Courteney Cox聽Were There for Each Other for Every Milestone:聽While they might have met on聽Friends 24 years ago, the real Rachel Green and Monica Gellar are best friends in real life 鈥 and their friendship has seen them through marriages, divorces, childbirth, new TV shows, and remarriages.

Cox named Aniston as the godmother to her now 13-year-old daughter Coco, and when Aniston wed her hubby Justin Theroux in a super-private ceremony in 2015, she did it with Cox standing beside her as her maid of honor.

5. When Francia Raisa Saved Selena Gomez鈥檚 life:聽This one still gets us a little teary-eyed.聽Gomez revealed last year via Instagram that due to complications from lupus, she needed a kidney transplant in聽order to save her life.

And in an ultimate act of friendship, her best friend Francia Raisa donated one of hers to the 鈥淲olves鈥 singer. Gomez thanked her friend, writing, 鈥淭here aren鈥檛 words to describe how I can possibly thank my beautiful friend Francia Raisa. She gave me the ultimate gift and sacrifice by donating her kidney to me. I am incredibly blessed. I love you so much sis.鈥

Raisa responded in kind by writing, 鈥淚 am beyond grateful that God would trust me with something that not only saved a life, but changed mine in the process.鈥

The pair met when they were both Disney Channel stars visiting a children鈥檚 hospital together back in 2007, and have been BFFs聽ever since.
