Penny Lancaster poses for rare photo with her two grown up sons Alastair and Aiden

Penny Lancaster is enjoying a dreamy holiday with her husband, Rod Stewart, and their two sons, Alastair, 17, and 12-year-old Aiden.

The family-of-four are currently on the other side of the world, and after spending some time in Australia, where Penny was pictured hitting the beaches in Sydney, they've now travelled to New Zealand.

Taking to Instagram on Thursday, the Loose Women panellist shared some photos of their time in the island country, including an incredibly rare photo of her alongside her two grown up sons.

In the snap, mother and sons appear to be posing inside a boat. Penny looks glowing in a warm knitted cardigan whilst cosying up to her youngest son Aiden. Alastair, who already towers over his rockstar father, can be seen resting his face on his brother's knee whilst smiling at the camera.

"My boys @alastairwstewart @aidenstew_1888 #newzealand #rainydays #happiness," she captioned the sweet post.

Over on her Stories, the proud mum shares more revealing holiday snaps, including a stunning "tattoo" which Aiden had drawn on her leg and another showing her on the boat again, but this time posing alongside a fish she had caught whilst fishing.

"We freed the little guy after," she told her followers whilst tagging "Rakino Island", a little island northeast of Auckland in the Hauraki Gulf.

Fans loved Penny's rare photo with her sons and were quick to point out who they resemble the most.

"Lovely photo of you mother and sons Penny," one wrote, whilst another added: "Handsome boys Penny.. youngest Rods double!"

"Isn’t the little chap the image of Rod. Bless him x," remarked a third.

Rod, who recently celebrated his son's incredible baby news as you can see in the video below, shares two sons with Penny, he is also a father to six more children. He was married to Alana Stewart from 1979 until 1984, and together they share Kimberly Stewart, 43, and Sean. In 1987, he welcomed daughter Ruby Stewart, 35, with model Kelly Emberg, and he also shares two children with second wife Rachel; Renee, 30, born in June 1992, and Liam, born September 1994. He is also a father to daughter Sarah Streeter, who was born in 1963 and placed up for adoption; the pair have since reconciled.
