Sweet sisters! Ireland Baldwin and half-sibling Carmen share cute interaction during family day in NYC with father Alec

They're half-sisters with the same famous father. 

And on Friday, Ireland Baldwin shared cute posts of her day with baby sibling Carmen on Instagram.

The 19-year-old model and the one-year-old toddler, whose father is actor Alec, played with each other during their fun-filled day with their 57-year-old patriarch and his second wife Hilaria in New York City.

In the video, Ireland can be seen sitting on the ground wearing a Harley Davidson-print T-shirt and distressed skinny jeans as baby Carmen waddles around her in a purple one-piece bathing suit. 

'She's giving me sideburns,' the eldest Baldwin said as the tiny tot plays with her brunette tresses. 

Ireland has recently been spending time with her family in the Big Apple including cousin Hailey.

She was put in a nostalgic mood as she spent time with her father Alec in New York on Thursday.

Ireland was spotted nuzzling a baby doll during a leisurely outing with her dad and step-mother Hilaria, 31.

The starlet also clutched a pint sized baby bottle as she tightly embraced the figurine, which was bundled up in pink clothing.

Ireland's doll more than likely belonged to her half-sister Carmen who held her 57-year-old father's hand. For the outing, Ireland sported black leggings, trainers, and a bright Varsity jacket.

She also slicked her hair up into a no-fuss bun and slung a leather purse over her shoulder. 

Earlier that day, Ireland displayed a little more than intended when she got caught in a downpour.

The daughter of Alec and Kim Basinger forgot her bra and was wearing just a thin black T-shirt as she got drenched while on an outing in New York with her cousin Hailey Baldwin.

There was no doubt the 6ft 2in beauty turned heads as she walked down the street while shopping on the Lower East side.

Ireland met up with fellow model Hailey, 18, for a morning snack before the duo got caught in the rain on their shopping spree.

The pair laughed as they were caught in the storm with Ireland using her shopping bag to try to shield herself from the drops. 

Hailey wore a rocker-inspired colbalt blue mini-dress with stud detailing, and chunky black boots.   

Despite the rain, Hailey kept her black sunglasses on as she clutched her cute leather handbag while crossing the street.

Ireland also enjoyed some time with Hilaria earlier that day, who showed off her fit frame in an off-the-shoulder grey top and Daisy Duke shorts. She held onto a beige Louis Vuitton purse.

Hilaria looked amazing after giving birth to baby son Rafael seven weeks ago.  

That may be because Hilaria - who gave birth to her son Rafael just one month ago - takes good care of herself with consistent yoga workouts and a very healthy diet, which she illustrates on her Instagram account.

While shopping for lingerie together at La Petite Coquette, the ladies appeared to be the same age.   

Leggy Ireland towered over the mother-of-two wearing casual leggings. 

Also seen briefly was Alec, 57, in a black T-shirt and army green trousers. 

Ireland looked healthy and happy on their outing, after leaving rehab in California two months ago.

The model has had a difficult year, breaking up with rapper girlfriend Angel Haze and entering a rehab facility to deal with  'emotional trauma' in April.

The tall beauty spent three weeks at Malibu's SOBA Recovery Center before checking out in May, although she continued to receive treatment.
