The 23-year-old model – whose father, Alec Baldwin, is the brother of Hailey’s father Stephen Baldwin – has heaped praise on the married couple, saying they’ve “helped each other grow”, and are now “learning the ways of love and marriage” together.

Ireland said: “I think that they really complement each other. I think that they’ve really helped each other grow because before … they started off having a lot of growing to do. They were just not ready. They were really young and they had a lot of growing to do and a lot of life to experience, and I think they both now are experiencing things together and learning the ways of love and marriage – not that I know those ways.”

Although Hailey and the ‘Love Yourself’ hitmaker are already married – after having wed the same day they received their marriage license last year – they’re still planning a larger ceremony for friends and family.

Ireland admits she isn’t “really doing much” to help Hailey plan her big day, but said the 21-year-old model doesn’t need it, because she’s in “full wife mode now”.

The beauty told Us Weekly magazine: “I am so happy for whatever they are deciding to do. I love Justin and I love Hailey. I love spending time with them. … She’s my little cousin, like my little baby, so I’m so excited to see her growth and her beautiful house that she’s living in. She’s full wife mode now, so I love it.”

Previously, Hailey’s older sister Alaia claimed she had no idea what was happening with the couple’s wedding, as the pair kept changing their plans.

She said: “We will see. Who knows what their plans are. They’re very up and down, so I just I’ll be there at some point in a dress, in sweats – we don’t know!”
