They've seen their relationship grow from strength-to-strength since they started dating two years ago.
And Myleene Klass was supported by her handsome boyfriend Simon Motson as they headed home after she co-hosted the Classic BRIT Awards at London's Royal Albert Hall on Wednesday night.
The TV and radio personality, 40, looked stunning a floor-length backless white gown with pearl detailing as the couple left the event hand-in-hand.

Keeping her look sleek, the classically-trained musician pulled her tresses off her face into a bun on top of her head, drawing attention to her high cheekbones.
The mother-of-two opted for a bold red lip to add a pop of colour and applied lashings of mascara to create a showstopping effect.
Myleene's beau, fashion PR guru Simon, looked handsome in a classic double breasted black tuxedo, as he clasped her hand.

Work some white in a gown like Myleene's
Myleene Klass co-hosted the Classical Brit Awards last night and wore a rather fabulous gown by Nadine Merabi for the occasion.
But as she was spotted leaving the glamorous event she had changed into this slinky dress by Reem Acra. Now, this is actually a look from the designer's SS18 bridal collection so is Myleene hinting to her boyfriend Simon Motson we wonder...
She certainly looks lovely in the halterneck creation and we love its embellished neck and contrasting black bow. It's beautifully cut and really accentuates her killer figure. It isn't available to buy oline but you can shop Reem Acra's ready-to-wear line at Net-a-Porter by clicking to the right now.

When the pair went public with their relationship in May last year, the brunette raved of their romance to the Daily Mirror: 'He is so hot. It's lovely. I'm enjoying myself.'
Her new found love comes five years after her failed marriage with the father of her two daughters, Graham Quinn, 41.
The bodyguard walked out on her 34th birthday in April 2012 putting an end to their love, with their divorce finalised in 2013.
Discussing her devastation, she admitted to Woman magazine: 'I thought I'd never smile or trust anyone ever again'.

Trim: Myleene works hard to maintain her enviable figure, revealing recently that she boxes to stay in shape and feel good
'I felt so betrayed and so crushed. But I couldn't wallow in it. I said to my mum and dad, "I'm broken, but I will not sink."'
Since turning 40, Myleene has been making more of an effort to hone her physique and she has incorporated boxing to help her keep fit.
She told Hello magazine in February: 'I've put more effort into thinking about what I put into my body, how I use my body.
'I want to stay fit for my girls and set an example to them. I want to feel strong. I've incorporated boxing into the workout because I love how it makes me feel afterwards.'
