Sharon's birthday celebration would not be complete without drama superstar Judy Ann Santos. 

Juday and Sharon are very close, with the latter serving as matron of honor to the former's intimate early morning wedding to Ryan Agoncillo last year.

The mother-daughter tandems of Zsa Zsa Padilla and Karylle, Sharon and KC, took turns in singing "Sana'y Maghintay ang Walang Hanggan."

Ai-Ai delas Alas and Sharon relived the jukebox hits, "Isang Linggong Pag-ibig" and "Tukso."

Sharon and Ai-Ai were seen together last year in Star Cinema's comedy offering, Best Friends Forever.

Sharon Cuneta tried her best to keep up with Mr. Pure Energy Gary Valenciano.

The two stars sang and danced "Hataw Na" and "Shout for Joy."

KC Concepcion teamed up with dancer-actor Vhong Navarro (seated) for an upbeat number.

KC's performance is always highly anticipated by loyal supporters of her mom, who all witnessed her grow from a shy toddler to a true celebrity.

Robin Padilla offered a bouquet of flowers to the birthday celebrator.

Sharon and Robin were considered Viva Films' top artists during the '80s until the early '90s. They were also romantically linked for a time.

"Single ako!" Robin playfully told Sharon. He attended the concert with his son Ali.
