Los Angeles, March 24 (AZINS) Singer-actress Miley Cyrus and actor Liam Hemsworth has sparked speculation that they are planning on starting a family soon.

While there are reports that Cyrus and Hemsworth have secretly married following a cryptic Instagram post, the couple has now sparked baby rumours as they have started constructing a children's playground and nursery on their Malibu property, which includes both of their homes, reports dailymail.co.uk.

One of the studios on their 10-acres ranch had been transformed into a play area.

"You are my sunshine" Cyrus wrote on the wall of their music studio.

In a photograph obtained by the publication, there is a huge dinosaur next to the pool.

However, the playground seems to be built to represent Cyrus's childlike and artistic nature.

The giant dinosaur in the yard is reminiscent of the toys she had in the backyard of her previous home which included a life-size horse, teepee and Hollywood sign.
