Paris Hilton and Lindsay Lohan have become good mom friends decades after feuding

Appearing on Watch What Happens Live with Andy Cohen this week, Paris - who has Phoenix, three, and London, two, with her husband Carter Reum - said: "We are planning to get the kids together.

"I am so happy for her. She is glowing. We love being moms."

As for the Freaky Friday star, she has a two-year-old son, Laui, with her spouse, Bader Shammas.

Paris previously offered some advice on motherhood to Lindsay.

She told Access Hollywood: "I'm so excited for her.

"I just feel so happy for her and it's just exciting to see all of my friends growing up and starting families on their own, and my advice is just to soak in every moment. It's just so precious."

Paris added: "Everyone is just saying they grow so fast. So just to enjoy the little baby moments when we're just, like, snuggling and he's just a little, tiny angel."

The high-profile duo endured a much-publicised feud that dates back to 2006, when Paris laughed as her pal Brandon Davis rubbished the actress in an interview.

At the time, Brandon said: "I think she's worth about $7 million, which means she's really poor. It's disgusting. She lives in a motel."

Brandon also made disparaging remarks about Lindsay's body, describing her as a "fire crotch".

He asked: "Who would want to f*** her?"

However, a spokesperson for the heiress subsequently denied that she shared Brandon's views.

He said: "It is unfair to characterise Brandon's statements as being reflective of Paris' feelings about Lindsay. We're dealing with two different people.

"It was Brandon who was speaking, of course there are moments when Paris was laughing, but she never said anything."

But their feud escalated shortly afterwards, when Lindsay shamed Paris for her infamous sex tape.

She quipped: "Obviously, she's very comfortable making videos."
