Last month, Sophie Monk and her partner of two years, Joshua Gross, announced their engagement.

"I'm engaged," Monk shared on Instagram at the time.

"I honestly can’t thank you enough for all the love and support. I know I have the coolest people following me and you’ve always had my back and I feel so cared about. You’re absolute bloody legends," she continued.

"I’m not very good at being mushy. I’m trying to say I absolutely adore you. Joshua and I are so happy."

Gross, 37, who is a neurosurgical robotics consultant, also shared the news on his own Instagram page, writing: "Luckiest guy in the world."

Now, almost one month after announcing their engagement, Monk has shared how Gross proposed on Christmas Day at home while enjoying a cup of coffee, in an interview for Stellar magazine.

"He knelt down, and I just said yes before he even asked," she told the publication.

"He's like, 'Hang on, I've got stuff to say!' And I'm just like, 'It's good, yes!' And then I cried."

Gross also revealed that he was "a little heartbroken" when he saw paparazzi photos of him leaving a jeweller in November, which spoiled the surprise.

"I'd gone through six months of cloak-and-dagger secrecy to get this done without Sophie knowing because I wanted her to have a good surprise," he explained.

"Everything is so public for her, I thought this is one thing we can have behind closed doors. So that was a little heartbreaking. I was planning on proposing a little earlier and (the media attention) sort of paused things for a while."

Sophie added: “There was a paparazzi shot of him leaving Luke Rose, so I kind of guessed – and my heart broke for the surprise. But then I guess I was prepared in a way."

The couple also shared that they're planning on having a more intimate wedding and they're looking to start a family in the future.

"We'd like a family, for sure. It's just about timing," Sophie said, adding that they'll "play it by ear" with their work schedules.

The formerBachelorette previously spoke about her decision to undergo embryo freezing with Gross in October last year.

"We both want a family so he’s all for it," she said during a webinar with Monash IVF.

"I’m very supportive," Gross added.

"I did it obviously because I want a family," she continued. "You always think 'oh it'll happen' and you'll meet the right person. So I never really worried about it and I kind of hit 30 and I was like, 'Yeah, I'm still cool' and then I blinked and I was nearly 40 and I was like, 'Oh, God.' Before you know it time's gone."

The 41-year-old also explained why she didn't do it earlier.

"I didn’t have the right partner, now I do and I’d like to do that. I’d love to try and have one," she said. "It’s just peace of mind me knowing that it’s there."

How Sophie Monk and Joshua Gross met.

Monk and Gross first met on a plane back in 2018.

"I had just finished filmingLove Islandin Mallorca and was on my way to San Francisco for a random TV gig with Channel Nine when I made a last-minute decision to go back to Australia," Monk told the Sydney Morning Herald last year.

"I sat next to Josh in business class and we started chatting. About two hours into the flight, I asked him if he was single. He responded yes. I then asked if I could kiss him. I was clearly out of practice and a bit of a nerd so I went to brush my teeth and thought, 'Let’s do this.' We had 16 hours to go."

Speaking to Stellar in 2019, the television presenter shared that she knows Gross is "the one".

"He’s everything I want in a person and more... I don’t think you could invent a better person for me. I’ve gone for something completely opposite to what I’ve ever gone for," she said.

"He’s a man; a grown up. He’s really sweet without being annoying, and he’s calm and makes me feel safe."
