Morissette couldn't hide her thrill over being noticed by the original singers of "Secret Love Song," a soaring ballad that she frequently includes in her repertoire and which has become her most watched cover on YouTube, with 75 million views and counting.
In particular, Jade Thirlwall, one-fourth of the British girl group, posted clips of Morissette performing the song on her Instagram Stories Monday. The performance, from the 2017 Asia Song Festival in Korea, was being watched on a TV screen apparently by a group, going by the audible reactions.
"Oh, I love her!" one could be heard saying, as Morissette hit a climactic note.
"Jesus!" another voice said.
"Oh my gosh," went another reaction, followed by the group cheering.
In both clips shared by Thirlwall, she notably tagged the official Instagram account of Morissette. She also captioned the second video with, "Is @itsmorissette real?!", in an apparent expression of disbelief over her singing voice.
Morissette caught wind of Thirwall's posts and at once took to Twitter to share her excitement.
The "ASAP" artist wrote: "Don't mind me, I'm just literally shook at the moment! Jade of Little Mix shared clips of their team watching my cover of 'Secret Love Song' at the Asia Song Festival on her IG Stories!
"Even heard Perrie comment too, so they all must be watching! OMG, thank you loads for noticing!"
Morissette was referring to Perrie Edwards, another member of Little Mix, along with Jesy Nelson and Leigh-Anne Pinnock.
In a subsequent tweet, Morissette shared a screenshot of Thirwall following her on Instagram, captioned: "Ito pa mga mamsh! #idie #legit #sorrynotsorryforfangirling"
Morissette, a "The Voice of the Philippines" runner-up whose talent has nonetheless earned her strides in her music career, is a favorite subject among an international community of YouTube "react" channels, where vloggers record themselves watching performances for the first time.
One of her most reacted-to performances is her "Secret Love Song" rendition recorded live on the popular "Wish 107.5 Bus," the channel's most watched video with some 75 million views.
