Out singer Adam Lambert has reacted to a petition calling for his removal as headliner of a New Year's Eve concert in Singapore.

More than 20,000 Singaporeans signed the iPetitions.com petition. Opponents of Lambert's inclusion objected to his “active promotion of a highly sexualized lifestyle and LGBT rights,” saying that both “are contrary to mainstream Singaporean values.”

In a Warner Music Singapore Facebook post promoting a counter petition in support of his appearance, Lambert said that he's a “uniter, not a divider.”

“My performance at Celebrate 2016 will not only be a spectacular one, it will celebrate the entire human family in all its diversity,” Lambert said. “I am a uniter, not a divider, and I believe in celebrating the human heart and spirit.”

Nearly 25,000 people signed the counter petition which “denounced” and “condemned the obvious sexual orientation discrimination demonstrated by the other petition on this site that is against Adam Lambert performing in Countdown 2016.”

“I have put together an entirely new show experience for my fans that is kicking off in Singapore,” Lambert continued. “The Original High tour is based primarily on new material, and it promises to be a thoughtful and sophisticated insight into the pursuit of happiness and self-worth. There is no better time for celebration than at the moment one year changes into another, so I hope you will join me to celebrate the future and 2016.”

Event organizer MediaCorp has confirmed that Lambert will headline the show.
