Even Reese Witherspoon can’t believe how many Hollywood A-listers pitched in to help her ring in her 40th birthday.

The actress, who celebrated the milestone occasion on Tuesday, took to social media to thank the slew of stars who helped make her big day special, including Sofia Vergara and even her Cruel Intentions costars.

Posting a collage of new – and old – photos, Witherspoon wrote on Instagram, “Awww…Y’all are the sweetest!!”

“THANK YOU SINCERELY for all the birthday love,” she added. “#MakingMeBlush.”

In addition, Witherspoon responded to celebrity tributes on Twitter, including those from Elizabeth Banks and Julianne Moore.

Over the weekend, the actress partied the night away at the Warwick in Hollywood, California, alongside her husband Jim Toth and a long list of her A-list pals that included Jennifer Aniston and husband Justin Theroux, Matthew McConaughey, Nicole Kidman, Kate Hudson and Taylor Swift.
