She announced in March that she is expecting her third child, and Hilaria Baldwin can't wait for the little one to arrive.

The 32-year-old was spotted enjoying a stroll in New York City on Wednesday with husband Alec, 58, and their son Rafael, who turned one last month.

That morning, the family went to Hilaria's ultrasound appointment, and she shared a photo to Instagram which showed her revealing her bump as the doctor checked on her baby's progress.

'Little #BaldwinBabyBump3 update: all is wonderful!' she captioned the picture. 'I'm getting REALLY excited to meet him! #366daysoflivingclearly #HilariaLCM.'

Hilaria looked comfortable but stylish as she headed to the appointment with Alec and Rafael, dressed in a patterned white and grey empire line dress.

The maternity frock covered her growing belly but left her legs on show, and the yoga instructor teamed it with flip flops and large sunglasses.

Hilaria held an iced beverage in one hand and used the other to push little Rafael along in a pink toy car.

Meanwhile Alec, who was clad in a simple grey T-shirt, black trousers and trainers, held onto their two pet pooches' leashes.

The happy couple married in June 2012 after a year of dating, and are also parents to daughter Carmen, who turns three in August.

Alec also has 20-year-old model daughter Ireland from his marriage to Kim Basinger. The pair married in 1993 and separated in 2000, finalising their divorce two years later.

The actor said earlier this year following Hilaria's pregnancy announcement that the news came as 'a surprise', and added that they don't plan to have any more children after their third.

He told Extra: 'We wanted to have another one, maybe not so soon, we thought about taking a year or two off.

'They come when they come, but this is it. We're going to have one more then we're going to enjoy them, all three of them.'
