She was in town to perform at a pool party concert.

But just before taking to the stage, Hailee Steinfeld pampered herself with a bit of R&R poolside after jetting into Miami on Friday.

The bikini-clad 19-year-old put her flat belly and long legs on show as she sat in the shade at a hotel beside her mother, Cheri.

Periodically glancing at her phone through her large sunglasses, Hailee wore her long tresses down in a beachy and side-swept hair ‘do which cascaded down in loose waves.

The actress sprayed on some sun block to protect herself from the summer sun, while her mother curled up nearby with something to read in hand.

Hailee looked relaxed as she lounged beneath the shade, digging into a juicy burger before grabbing her towel to head on out.

The actress was in Miami to headline the iHeartRadio Summer Pool Party concert on Saturday alongside the likes of DNCE, Jason Derulo, Tinashe, and Kygo.

There, the Begin Again actress kept it simple in a sleeveless black maxi dress teamed with a white bikini top.

Hailee released her first EP album and hit single Love Myself last year.

‘It’s about how much power there is in self-love and being able to provide for yourself,’ the actress described the song to Harper’s Bazaar.

‘I don’t think loving yourself is easy, but I’m realizing the importance of it more and more.’

Hailee also revealed that she’s open to dating, although she doesn’t say if there is one special person in particular right now.

‘I mean, there’s always time for dating,’ said the starlet, who refers to book Date Like a Man for tips.

‘I do feel that right now, though – and I hate saying this – my top priority is what I’m working on. It’s that and family, and then everything else.’
