Ciara was thrown a surprise superhero-themed party in celebration of 30th birthday on Saturday night (24.10.15).
The 'Body Party' hitmaker was reduced to tears when she arrived at the Warner Brothers lot in Burbank, California, and was greeted by her friends and family to mark the milestone.
A source told PEOPLE.com: "Ciara was overwhelmed with emotion and began to cry tears of joy."
The brunette beauty's boyfriend Russell Wilson, 26, had arranged the festivities at the 'Batman' exhibition and had asked all the guests to dress up as superhero characters.
Ciara had no idea that a celebratory bash was being thrown for her as she thought Russell was treating her to a viewing of the upcoming film 'Batman v Superman: Dawn of Justice.'
The talented starlet's beau had told her glam team to dress her in a skin-tight latex Catwoman suit and a black mask.
Ciara's 17-month-old son Future Zahir, whom she has with rapper Future, was in attendance and had guests cooing over him as he wandered around in his Superman suit.
Kelly Rowland, 34, and Lily Collins, 26, were also there to celebrate their pal's 30th birthday and couldn't resist documenting the festivities on their social networking sites.
And the best dressed was awarded to Beyoncé, 34, who turned up to the party as Storm from 'X Men'.
The insider concluded: "All the guests dined on sushi and danced into the evening."
