Kelly Clarkson's four-year-old daughter has set her sights on marrying rocker Chris Martin after developing an obsession with Coldplay's hit Yellow.

The Since U Been Gone hitmaker shared a sweet video of herself and little River Rose discussing her crush on the Coldplay frontman on Twitter on Tuesday (07Aug18), when the tot also showed off her rendition of the 2000 single, pronouncing the title as "Lello".

"I like him and he's beautiful," she smiled to her mum. "I like his song and I wanna kiss him!"

Laughing at her girl's brazen behaviour, the singer quipped, "You wanna kiss him? You can't kiss him!"

"I love that you love Chris Martin," Kelly gushed after River delivered a few lines of her favourite song. "You have good taste."

The 36-year-old, who shares River and two-year-old son Remington with husband Brandon Blackstock, shared a little more detail about her daughter's huge crush in the post's accompanying caption.

"So my daughter wants to marry Chris Martin and is obsessed with his song 'Yellow,'" Kelly explained, revealing the toddler fell in love after watching the track's promo, which was filmed when the British musician was 23.

"She wants to marry the boy in the video, which I have informed her he is not a boy anymore and has kids older than her but she will have none of it, she is determined," added Kelly.

Chris, who is dad to daughter Apple, 14, and son Moses, 12, with ex-wife Gwyneth Paltrow, has yet to comment on the cute clip, but the 41-year-old is already taken - he's been dating actress Dakota Johnson since last year (17).
