Lottie has also spoken positively about the effect Themy has had on her life. She has credited him with helping her become more mature and changing her perspective on romantic relationships. Perhaps most notably, she has indicated that her famous half-sister, Kate Moss, and other family members have welcomed him.

Instead, his professional background is associated with the art market and business.

The pair are therefore close in age.
Although their relationship has received media attention, Themy has not shared extensive personal details publicly.
His professional background and appearances alongside Lottie remain the main sources of information about him.
As their relationship becomes more visible, fans may naturally become curious about his family and early life.

Lottie has spent much of her adult life in the public eye.
As Kate Moss’s younger half-sister, she attracted attention from the fashion industry at an early age.
Her modeling career and television appearances later expanded her public profile.
The decision to share photographs with Themy therefore marked a new chapter in a personal life that has often attracted outside interest.

Lottie Moss and Themy Kalaitzis have reportedly moved in together in London.

Moving in together is a significant step for any couple.
It involves adjusting to everyday routines, balancing work responsibilities and spending more time together outside romantic holidays or public events.
For Lottie and Themy, their different professional backgrounds may also mean managing contrasting schedules.
Lottie works in modeling and entertainment, while Themy’s career is connected to business and the art industry.
Although the couple have shared some details about their relationship, they have not publicly disclosed every aspect of their living arrangements.

Kate is one of Britain’s most famous fashion models, while Lottie has developed her own career in the industry.
Although they share a family connection, their professional experiences and public identities are different.
Themy’s reported acceptance by the family appears to be a meaningful development for Lottie.
