Halsey playfully poses in busty tennis whites and gushes she's the 'luckiest' while sharing adorable snap of her newborn baby boy Ender

She is the proud mum of son Ender, who she welcomed with boyfriend Alev Aydin in July. 

And Halsey told fans she feels the 'luckiest' as she shared an adorable snap of her baby boy to social media, after taking her own merchandise for a test run. 

The singer, 26, looked incredible as she playfully posed in a tennis-inspired white two piece, before modelling a new sweatshirt from her merchandise collection and a bandana. 

Halsey treated her Instagram followers to a new reel, where she was seen working the camera in a white pleated mini skirt and a sheer collared top that left little to the imagination. 

The busty cropped design was almost see-through and made sure to highlight the star's incredible frame. 

Sporting glam make-up, Halsey wore her short raven-coloured locks down and tucked her hair behind her ears while her blunt bangs framed her face. 

The Without Me hit-maker flashed a look at the tattoos on her arms before reaching for the green sweatshirt she designed and pulling it over her outfit. 

She then grabbed a maroon and white bandana and tied it around her head, before topping up her lip gloss while using the camera as a mirror. 

Halsey teased: 'Trying on my own merch because what are you in this life if not your own biggest fan.

'sooo CUTIE!!!! ps I fought for the bandanas, im obsessed. shop.loveandpower.com (sic).' 

If that wasn't enough to excite fans, Halsey then treated her 26million followers to a new snap of her month-old son Ender, who she welcomed with partner Aydin in July. 

She shared a photo of her dad cradling Ender on his chest and made sure to hide the tot's face from view with a frog emoji. 

Gushing over her baby boy, Halsey captioned the adorable photo: 'I am the luckiest.'

Halsey and boyfriend Aydin were first romantically linked in 2019 after the couple was spotted sitting together during a Los Angeles Lakers game. 

The couple confirmed they were expecting a baby together in January earlier this year, with Halsey announcing son Ender's arrival last month on Instagram. 

She shared a black and white shot of her cradling her newborn in her hospital bed, with Aydin sat alongside her and wrote: 'Gratitude. For the most “rare” and euphoric birth. Powered by love. Ender Ridley Aydin 7/14/2021.'

Halsey's latest post, meanwhile, comes after Taylor Swift was seen supporting the mum-of-one and her new album titled If I Can't Have Love, I Want Power. 

Taylor urged fans to purchase Halsey's album, while revealing she was 'blown away' by her pal's new music. 

The vocal talent tweeted: 'I’m blown away by @halsey’s artistry and commitment to taking risks. Giving us all a brave new era to dive into and explore together. 

'If I can’t have love, I want power is out now- please stream and buy the album!!'

Halsey replied: 'Thank you T... means so much.'

Speaking about the album, Halsey had shared a first look on Twitter and told fans: 'I have waited my whole life to be exactly where I am right now, and at times I have enjoyed the darkness along the way. It’s now your turn.'

The record is her fourth studio album and produced by Trent Reznor and Atticus Ross.
