Reese Witherspoon was a total fangirl for Dolly Parton when she met the country music legend during her concert at the Hollywood Bowl on Sunday night.
And even on Monday, she was still reeling over the experience. "Today's #MondayMuse?! The incomparable @dollyparton, who made my musical dreams come true last night!" Witherspoon captioned a photo of herself posing with Parton. "You're a legend Dolly. I will always love you! #DreamsDoComeTrue #DollywoodBowl."
She later Instagrammed an older photo of the 70-year-old musician, writing: "Today's mood.... courtesy of last night's @DollyParton concert."
The 40-year-old actress -- who won an Oscar for her portrayal of country music icon June Carter in Walk the Line -- also got quite the surprise when Parton gave her a shout-out during the performance. "Nearly passed out when @DollyParton said my name," she tweeted.
Even before the concert started, Witherspoon was sharing her excitement over getting to see the "9 to 5" singer hit the stage. "Can't contain our excitement ... @dollyparton here we come!!!" she captioned a video of herself and friend Shannon giddily anticipating Parton's performance.
"It's written all over my face, couldn't be happier at the #DollywoodBowl!!" she exclaimed in another caption.
Witherspoon also posed with her friends and a tote bag that read: "What would Dolly do?"
"Girls night with these ladies and @dollyparton," she wrote. "Doesn't get much better than this!"
While Parton didn't mention Witherspoon by name on social media, she did share an Instagram pic from the concert. "The stars are out in Hollywood! #pureandsimpletour," she wrote.
Last month, Witherspoon revealed to ET that she's also a fan of Drake's music, regardless of what her three kids think. "I think I embarrass them terribly when I try to sing Drake songs," she admitted with a laugh. "I don't stop singing. I enjoy it."
