Xian Lim only invited four special guests to sing and perform with him: Martin Nievera, Jona, KZ Tandingan, and Matteo Guiddicelli for Songs in the Key of X at The Theatre in Solaire.
However, fans who helped organize the concert knew there was a very, very special guest sitting right in the audience. They kept shouting her name, especially during more mellow love songs where Xian played the piano.
We tracked all the moments on- and off-stage where Kim Chiu became the evening's fifth special guest.
1. When the camera was able to get a quick glimpse of Kim Chiu in the center.
Kim sat down at the third row while Xian did a medley of April Boy Regino songs.
She was smiling and giggling like a school girl. KimXi fans immediately reacted.
2. As Xian got ready for his next song after his powerful Jona duet, fans start to shout "Andito si Kim."
Xian responds, "Andyan nga talaga?"
As he sets up for his song, he says, "Iniisip ko pa lang, Kim..."
Their fans go wild and scream.
Xian continues, "Inisip pa lang kita biglang nanlamig ako."
Trying to locate where she is seated, as the camera now shows her in her seat, focused on her face, Xian says, "Sabi sa 'yo huwag kang magpapakita, e."
Kim starts to duck as people are crowding around her seat.
Xian says from the stage, as he starts to walk down, "Hug, hug lang, hug..."
When he's about a meter away, Kim stands up as Xian keeps saying, "Hug, hug lang daw."
Kim takes her time before standing up to remind him, "Hug lang," as she smiles and Xian pulls her in.
He then says out loud, "Kakanta ka?" to which Kim playfully boxes him in the arm.
He tells her, "Thank you for coming," as he sneaks a quick kiss on her forehead/temple area.
3. Backstage, after the concert, Xian tells us about seeing Kim in the audience.
"Natuwa ako sa kanya," he admits as he first spotted her.
"Nahihiya siya," pointing out that the cameras were relentless.
He told us why he asked for a hug, "Sabi ko, pahingi ng isang hug para pampaano ng tension you know."
"Game naman siya."
Xian adds, "Tawang-tawa ako sa kasama niya, si Patty, yung katabi, hiyang-hiyang kasi nakafocus sa face nila."
4. Xian's song for Kim
He explains, "I think it's a bit obvious, nung kinantahan ko siya."
Right before singing Fra Lippo Lippi's "Beauty and Madness," Xian went in for the hug, "She likes that song kasi."
5. Prior to the concert, Xian confesses that he asked for a special favor from Kim.
"Sabi ko sa kanya, huwag muna tayong magkwentuhan kasi mas kinakabahan ako kapag naririnig ko yung boses mo," he says with a huge, happy grin.
Kim asked him, "Pwede daw ba uupo siya sa harapan."
Xian immediately told her, "Huwag ka umupo sa harapan, lalo akong di makatugtog niyan!"
6. That moment when Matteo is about to spill the beans.
When Matteo was onstage, he recalled how long he has known Xian.
"I gotta say something very important... I know Xian."
"We started off our careers almost the same year," to which Xian says, "the same year!"
Matteo continues, as Xian looks on, "I know so many secrets."
"If you guys wanna know... Just scream."
The audience screams.
"Okay you gotta scream louder than that. I know so many love secrets. I can list like more than 10, brother."
Xian reacts, "Ha? Huwag, huwag."
Matteo barrels on, "Like how you and Kim met, how you fought in Hawaii before."
Xian smiles, "We fought?"
Before it turns into more, Matteo says they are going to sing "Treat You Better."
He jokes, "Why? Who is it dedicated to, Xian?"
Xian responds, "It's not dedicated, you chose this song!"
Matteo then issue a challenge, "Come on, Xian will treat Kim better than Justin Bieber."
Xian just laughs as he heads to the piano, "What? What?"
Matteo ends, "Justin Bieber, bwisit na Justin Bieber na 'yan, message pa ng message kay Kim."
The former racer shouts, "Justin Bieber, this is for you!" as they do a duet of "Treat You Better."
7. When Xian danced Despacito.
Backstage, Xian issues another challenge, "Justin Bieber, watch my Despacito!"
He adds, "It's all fun and games.
Through his Instagram account, Xian expressed his gratitude for his guests by posting:
