Lauren Jauregui gushed about her ''infinite'' love for her boyfriend Ty Dolla Sign on Valentine's Day (14.02.18).

The Fifth Harmony star took to Instagram account to share ten adorable photographs of the pair in a touching tribute to her beau - whose real name is Tyrone William Griffin, Jr. - while revealing how ''confident'' and ''warm inside'' he makes her feel.

Alongside the series of pictures, Lauren wrote: ''To say the least, I am in love with you. Just a little memory recap of the year with a 10 picture limit but, the love I have for you is infinite. You teach me, you push me to grow, you challenge me, you lift me, you make me feel safe and loved and confident and warm inside. Thank you for everything, mi amorrr Happy V Day, cheers to many more I'm right next to U lol (sic)''

Lauren also revealed the cute surprise the record producer had in store for her, sharing it her on her Instagram Story.

In the clip, the brunette beauty revealed how romantic rose petals were laid out as a trail which she followed down the stairs to a table, where he'd made a special breakfast for her.

When she sees the effort her boyfriend went to, a shocked and tearful Lauren says: ''What...?''

And text across the video reads: ''There are actual tears streaming down my face.''

The 'Sucker for Pain' hitmaker also shared a selfie with his girl on the photo-sharing app, captioning it with a red love heart emoji.

It seems the pair are now more than ''just vibing'', which is how the 21-year-old singer described her relationship with the 32-year-old hip-hop star last summer.

Lauren met Tyrone after they collaborated on the Fifth Harmony song 'Work From Home' in 2016.

Addressing rumours they were dating in 2017, she said: ''We're just, you know what I mean - we're just vibing. I don't want to talk about that.''
