Attending the New Look Men Wireless launch party in the capital, Calum and Ianthe made the perfect pair as they cuddled up together on arrival to the event.
Posing for photographers, Calum - who looked effortlessly cool in a colourful vest and cap - wrapped his arms around his new flame, while Ianthe nestled into him placing her hand on his stomach.
The former Made In Chelsea star looked gorgeous in her casual ensemble, rocking ripped jeans and a low-cut top.
Inside the party, the pair rubbed shoulders with the likes of X Factor group Rough Copy and a whole host of TOWIE stars - including Lauren Pope, Jessica Wright and Chloe Lewis.
Calum and Ianthe's outing in the capital comes after the pair recently enjoyed a romantic getaway together.
Last month, the couple jetted off to Abu Dhabi for a sun-filled break and Calum made sure to share plenty of pictures from their time away with his fans.
The 34-year-old reportedly began dating Ianthe last year - despite claiming to be single while starring on Celebrity Big Brother in January.
On his exit from the house, Calum admitted he had pretended to be single in order to win his place on the show.
"Celebrity Big Brother wouldn't touch me for years and I've worked hard for this chance - so I wasn't going to jeopardise it by saying I was taken," he explained.
In reality, he was actually already in a relationship and since then, the star has been proving he is happily loved-up.
