The stylist welcomed her first child, whose dad is One Direction star Louis Tomlinson, on 21st January, and posted a new picture to Instagram over the weekend.
Her beautiful image focused on little Freddie's tiny hands and featured the sweet caption: "Couldn't have asked for a better Valentine."
Briana rarely posts to Instagram although she boasts nearly 300,000 followers. Her last Instagram post was the day of Freddie's birth, showing her planting a kiss on her son in hospital.
Boybander Louis, meanwhile, shared the first picture of Freddie to his own Twitter account last month, showing the tiny boy snuggling in to his dad's chest. His caption read: "Meet my little lad, Freddie."
Briana's pregnancy news surfaced in July and was confirmed by Louis in August, when he told a US TV show that he was "buzzing" to become a father. The couple were never in a relationship but are believed to have shared a few dates earlier this year following Louis' split from long-time love Eleanor Calder.
Since then, Briana has stayed away from the limelight. She lives in California with her parents, and there have been reports that Louis was house hunting in a nearby area so he could be close to his son.
Louis is now dating actress Danielle Campbell.
