The on/off couple are said to be keen on tying the knot with a "small and simple" wedding so they can work on expanding their family.

An insider told US' OK! magazine: "[She] doesn't want everyone else weighing in on whether getting married again is the right.

"Casper's great with the twins [seven-year-old daughter Emme and son Max] and he really wants to have a baby of his own too. They've already started trying, and he'd love to be able to reveal on their wedding day that they're expecting."

The wedding is expected to be held at her home in the Hamptons, with guests being told it is a party rather than a wedding, similar to Jennifer Aniston and Justin Theroux who recently tied the knot.

Meanwhile, the 28-year-old dance choreographer previously revealed the 45-year-old beauty "crushes on" every dance routine he gives her.

When asked if she was his favourite client, he said: "I have a top four. Nicki [Minaj] and I just click really well and I love her music. Nick Jonas is so young but extremely focused and great to work with. Jennifer crushes everything that you give her. Jessie J is like a comedian. She's hilarious."
