The 32-year-old disgraced Olympian posted a snapshot which showed Kayla flashing her engagement ring as she placed a hand on his cheek and kissed him.

According to TMZ, he had booked a $700 mountain top landing tour through Orbic Air.

The package promises 'a 50-55 minute helicopter tour and 30 minutes of private time on the peak with a complimentary toast, dessert and a rose.'

They brought along a photographer to capture the moment, and were both dressed in formal attire, with Ryan in a blue suit and the 25-year-old Playmate in a tight green dress.

Make them green with envy in Kayla's Topshop dress

Ryan Lochte and Kayla Rae Reid have gotten engaged, and while that huge rock on her ring finger is pretty impressive, it was her dress that really knocked our socks off!

Of course we can't wait to see what Kayla's wedding dress will be like, but for now the little green number she wore when Ryan popped the question will keep us ticking over. It's from none other than Topshop and we love the crinkled effect of the plisse fabric. The rich emerald hue is perfect for this time of year, plus the wrap front is super flattering.

At just $68, it's a great way to update your wardrobe for the new season, so click (right) to say yes to the dress!

Alternatively, go green and shop our top alternative picks in the edit below. Apt. 9's dress at Kohl's is spot on, or play with textures in this velvety number by Club L at ASOS. Or if you want to keep things simple, Missguided is the place to go! Decisions, decisions...

He captioned his post: 'Memories forever!!! #thelochtes #LA.'

Kayla shared her own version of the picture, which was taken at a different angle, with the caption: 'Speechless. Absolutely beautiful. So in love with YOU.' 

The model, who likely had an idea that Ryan was going to propose, admitted she was scared before her first time on a helicopter.

But the pair looked like they were having the time of their lives as they shared Snapchats before and after the proposal.

He also told USA Today that he is ready to settle down with Kayla, after she supported him through the scandal which was sparked by him lying about being the victim of an armed robbery during the summer's Rio Olympics. 

Ryan explained: 'My family says, "Don't you think it’s a little too soon?" I’m like, "Can you put a time on love? Can you?"

'When I realized this was "the one" was when she stuck behind me through this. She still loves me and she's still right there with me. '

Speaking to DailyMail.com in August, the Olympian's stunning model girlfriend had hinted that they met on dating app Tinder.

'He was on Tinder. I might be on Tinder,' Kayla said with a smile. 'That's all I'm going to say about it.'

Kayla travelled to Rio to cheer on Ryan during the Olympics, but he played down their romance and claimed he was 'active' and 'available' on Tinder. 

However the athlete now regularly declares his love for the blonde bombshell on social media, and revealed that they had moved in together just over two weeks ago.

The swimmer was discussing the support he received after he was rushed by protesters when making his Dancing With The Stars debut.

'Especially my girlfriend, because I'm living with her now,' he told People. 'She's definitely just been so supportive.

'And my mom is calling me non-stop. I'm like, "Mom, stop calling me! I'm OK. I'm OK." She's like, "I'm just making sure you're OK!"'

Ryan is still in the dancing competition with Cheryl Burke as his partner, and is about to go into week five.
