Heidi Montag has some advice for frenemy Lauren Conrad!

It’s safe to say that there is no love lost between Lauren Conrad and Heidi Montag.

However, we were surprised to hear that reality star Heidi had nothing but kind things to say when asked about her former The Hills co-star’s wedding.

Asked by entertainment site Celebuzz as to what piece of advice she would give to newlywed Lauren, Heidi was particularly pleasant and lovely!

“I would just say, ‘Love is really selfless’. It’s really important to be selfless and not always have to be right. You should really think about the other person,” said the 28-year-old.

Not a single catty remark in sight.

Heidi also appeared to reference her and Lauren’s famous falling-out, as she added: “Spencer and I have sacrificed a lot to be together, so I think we definitely prioritise each other. That’s the secret!”

It seems like good advice, given that Heidi and Spencer are still going strong, but we wonder if Lauren will be taking on board anything that her frenemy has to say!
