WATCH: Lea Salonga Sings on American TV Series ‘Crazy Ex-Girlfriend’ Season Finale

Tony Award winner Lea Salonga performed the song “One Indescribable Instant” on the season finale of American rom-com musical TV series “Crazy Ex-Girlfriend.”

Lea plays Aunt Myrna and appeared on the show’s season finale titled “Paula Needs to Get Over Josh.”

Crazy Ex-Girlfriend is a musical-themed comedy that revolves around Rebecca Bunch (Rachel Bloom), a successful, driven, and possibly crazy young woman who impulsively gives up everything in a desperate attempt to find love and happiness.

The show’s season finale was aired in the US last April 18. Lea tweeted after it was aired.

I had to take a photo of myself in this gorgeous Reem Acra gown. The lighting could’ve been better though. – @MsLeaSalonga

Hey EW, it’s @MsLeaSalonga, and I’m taking over! First up is Santino, Rachel and myself on the @cw_crazyxgf set. We three don’t have a scene together, so I needed to take advantage of this!
