London, UK – Babies on the brain? While pop star Harry Styles was fully focused on his Together, Together tour, his fiancée, Zoë Kravitz, was spotted talking with his mom, who is apparently convinced the two will start a family soon!

Most recently, the Watermelon Sugar performer and three‑time Grammy winner thrilled his fans at Wembley Stadium in London.

The 32-year-old's partner has been a loyal supporter during his run so far, and at his latest London show, Zoë took the opportunity to chat with her mother‑in‑law.

According to Heat, sources say Harry's mom can hardly wait to become a grandmother.

"Anne is absolutely thrilled about Zoe becoming her daughter-in-law," an insider dished.

The 58‑year‑old is convinced that it's "only a matter of time" before Harry and Zoë start a family – and it could happen faster than expected.

"Anne has been surprised at how traditional Zoë is, and she thinks she would make a fantastic mother," the source added.

Anne firmly believes her son has finally found his dream woman, and according to an insider, she's also certain that Harry and Zoë will have a rather large family.

The love story between the British singer and the 37‑year‑old began about a year ago, when the two celebrities were spotted together in Italy's capital.

Over time, the stars kept appearing hand‑in‑hand in public, seeming to confirm the swirling dating rumors.

In April of this year, their surprise engagement was announced.

"Anne is over the moon that they've found each other. She can't wait to spend more time with Zoë," the source emphasized.

How things will unfold for the newly engaged couple remains uncertain. What's clear, though, is that Styles already has a clear vision for his future.

"I want to be fulfilled, and I want to be in great relationships with people... I want to have great friendships. I want a family. I want these things," the outlet quoted the singer as saying.
