"Words cannot fully express how thankful I am for you opening up your home to my family and friends today," Cheryl, 34, captioned a photo of herself and Leah at the event on Instagram.
"My heart is overflowing with gratitude and appreciation."
The bride-to-be continued in her post, "The fact that you said yes to being my maid of honor was enough, but you wanting to make everything perfect for me, means the world -- I will never forget this special day for as long as I live."
"Countdown to the wedding day has officially begun and I cannot wait to have you by my side! I love you. #CherylAndMATTrimony #GettingMarried #SayingIDo #BridalShower #Bride #MaidOfHonor," Cheryl concluded on social media.
Leah responded to Cheryl's heartfelt post with an Instagram message of her own.
"My bride to be @cherylburke!" the actress wrote, sharing a photo of Cheryl in a sexy, strapless white dress with polka dot heels.
"So honored to be your matron of honor. I am so happy for you and @matthewlawrence. Looking forward to being part of your next chapter... to be continued... Thank you to all who came and celebrated her!"
Based on photos shared on Instagram, Cheryl enjoyed a rainbow-colored cake and a few selfies with Easter-themed bunny ears. Her guests also apparently competed to make the nicest toilet paper wedding gown.

Cheryl and Matt got engaged in May 2018 on her 34th birthday.
Matthew popped the question at sunset while celebrating Cheryl's birthday in their Laguna Beach, CA, hotel room.
Cheryl and the former Boy Meets World, Brotherly Love, and Blossom star reportedly began dating in February 2007 and stayed together for about a year before calling it quits on their relationship in February 2008.
Cheryl and Matthew reconciled nearly a decade later in February 2017. In September of that year, Cheryl admitted to People she regretted letting her romance with Matthew end.
"When we first dated, we were both young and immature, and I was so new to this [celebrity] world," she revealed of why their relationship didn't work the first time around.
"Now we are both adults and feel balanced. He's such a great guy. He's so normal, considering we're in this crazy business. It's so nice to be able to come home to him... He's someone I definitely do see spending the rest of my life with."
Cheryl joined Dancing with the Stars all the way back in Season 2 and has won two mirrorball trophies since. The brunette beauty has graced the ballroom almost every season with the exception of only a few to pursue other career interests.
The pro dancer, for example, finished in second place on the first season of I Can Do That, losing to Nicole Scherzinger. The talent competition aired on NBC from May to June 2015. About The Author:Elizabeth Kwiatkowski
