Kaley Cuoco-Sweeting is shining extra bright tonight!

The Big Bang Theory actress received a special star on the Hollywood Walk of Fame Wednesday afternoon that she described as nothing short of "unbelievably sweet and overwhelming."

"I didn't write a speech, because I thought I would just speak from my heart and I already started crying in the car on the way over here, so I got that out of the way," she joked during the ceremony. "I still think they are going to call and say this was a mistake."

Wearing a bright Monique Lhuillier dress, the 28-year-old got emotional as she thanked her family, friends and John Ritter, a dear friend she worked with on 8 Simple Rules.

Kaley, who asked for a spot near her former co-star's star, was overjoyed when she found out the city would accommodate her request. 

"Like I said, he must be jumping off the walls right now," she told E! News after the ceremony. "I can't even imagine what's going on up there." She later described Ritter as "adorable" and "one of my favorite people."

Another man who received a special shout out was Kaley's husband, Ryan Sweeting.

"[To] my husband, Ryan, who has also dealt with a lot of Kaley days, you have no idea how much I love you," she shared. "This would not be the same without being able to share it with you today." Awww

When asked if she was going to celebrate with him later tonight, Kaley told E! News, "Hell yeah…It's Kaley day."

Today, the actress continues to work on the popular CBS comedy The Big Bang Theory. Thanks to series creator Chuck Lorre, who also spoke at today's event, Kaley can fulfill her acting bug as the fan-favorite Penny.

"This is a dream come true," she told the crowd of fans. "I'm forever grateful."
