DRESSED in a slinky bra top, hot pants and leather boots, she gyrated with celebrity guest Vanness Wu.

Dancing sensually to the beat of the music, her hands started roving all over her partner.

Both singers then pulled their bodies together, locked in an embrace, and almost kissed.

If you thought this was another steamy dance number from singer Karen Mok, look carefully.

It's not sex goddess Karen but her good friend, the goody-two-shoes Gigi Leung.

Gigi and Vanness had put up the hot number, which can be viewed on YouTube, before she handed the stage over to her guest star at her recent charity concert at the AsiaWorld Expo centre in HongKong.

Known for her clean, virginal image, the Hong Kong star surprised fans with her sizzling dance with the F4 member on 21 Dec.

As netizen, 143me, said: "Was that really Gigi?! The shock of my life! I didn't know she would have the guts to do that kind of dance. It's so not like the Gigi Leung I know."

Gigi is not the only one who knows how to turn up the heat.

Miriam Yeung does too.

At her concert shows in Hong Kong in October, Miriam and her rumoured-boyfriend and guest star, Louis Koo, surprised the audience with a passionate kiss.

Over in Taiwan, popular Taiwanese celebrity Show Luo also danced up a storm at his November concerts in Taipei with two of his three female guest stars.

He and Elva Hsiao did a hot Latin number, with him whipping off her mini skirt at the end. He also sweated it out with Rainie Yang in an energetic hip-hop act, with the sweetie-pie singer-actress wrapping her legs around him.

Then there's dancing queen Jolin Tsai who set temperatures soaring with her good friend, rapper-singer Stanley Huang, at her Dancing Forever World Tour a year ago.

She would lean over suggestively at Stanley while they belted out their duet Nice Guy. The bare-chested dude would bear-hug Jolin, eliciting wild screams from fans.

Even homegrown singer JJ Lin has also hammed it up on stage with his guest stars.

The most memorable would be the peck that he shared with local singer A-Do at the Just JJ World Tour concert in Taipei a year ago.

The two men kissed each other on the lips, to deafening screams from the 10,000-strong crowd.

Hong Kong stars have long entertained fans by shocking them at their concerts, especially consummate performers like the late Leslie Cheung and Anita Mui.

They were naturals at dazzling their fans not only with their flashy and outrageous costumes - Leslie, memorably, wore skirts - but sexy antics such as suggestive poses, salsa hot dances, and even kissing their guest stars or dancers.

Ms Koh San Chin, senior marketing executive with concert promoter Unusual Entertainments, said antics are nothing new or especially shocking.

She said: "It's all part of the act, to make the concerts visually exciting.

"At least it becomes a talking point and it makes people want to see the concert."

Indeed, fans seem to lap it up.

Concert-goer Victor Lim said that with variety programmes on TV, especially Taiwanese shows, becoming more gimmicky and raunchy, concerts have to be more entertaining.

The computer analyst, 28, added: "What is a concert without such antics? At least, it gives the audience an element of surprise."

But not all singers can pull off sexing up their concerts with such antics.

Added Ms Koh: "Young and hot stars like Rain and Elva can pull it off and make (their concerts) more exciting but you wouldn't see (older) singers like Tsai Chin or Fei Yuqing doing it."

In her next post, our Postwoman Alvis Wong writes about Asian singers and their sizzling onstage antics.

The latest example is Gigi Leung who sexed it up at a Hong Long concert earlier this month with guest singer Vanness Wu.

Other Asian A-listers, like JJ Lin and Jolin Tsai, have pulled in big names to up the sizzle factor on stage.

But are they going overboard in a bid to outdo each other?
