Appearing on Good Morning Britain, the singer made sure to glam things up for the occasion and we're loving her tailored look!
Donning a stylish blush two-piece suit, Alexandra put her washboard abs on display as she teamed her longline jacket and matching trousers with a cute turtle neck crop top.
Finishing her look the starlet wore a pair of black courts on her feet, accessorising her ensemble with large hoop earrings, a chunky silver watch and some serious Chanel arm candy.
On the beauty front, Alexandra kept her glossy locks sleek and straight, sporting flawless make-up and lashings of lip gloss on her lips.
Flaunting her fabulous figure as she headed into ITV, Alexandra later revealed the secret behind her looking so good.
"I run and sing at the same time," she told GMB co-hosts Ben Shepherd and Kate Garraway.
Explaining there is a method to her madness, the 26-year-old said her odd training regime not only keeps her in shape, but helps her stage performance.
"It creates stamina for the shows," she continued. "I'm on the treadmill trying to blast out [my songs] babes. I'll be honest, it's pretty difficult!"
Needing all the stamina she can get, Alexandra is heading on tour with 'The Bodyguard' after playing the lead role in the musical for three months in the West End.
As the show travels up and down the country, the 'Broken Heels' singer will be performing six shows a week, for nine months.
Speaking about 'The Bodyguard', Alexandra said: "It's such a privilege and an honour to take on this challenge. Whitney Houston of course made this role really famous, but I had a blast in the West End.
"It's made me a really happy girl and the happiest I've been in a long time."
When asked how she deals with singing such tricky songs night in, night out, Alexandra insisted she "never gets complacent".
"It can be difficult," she admitted. "But every night you have to go out there knowing that the audience is different [each night] and that people have paid good money to see a show."
As for her own music, Alexandra hasn't released anything for the last three years.
Promising fans new material this year though, she said she will be releasing an EP at the end of March, with a brand new album to follow later on in the year.
