The British model's latest birthday comes amid a big year for her and Saul, who got engaged in September, before announcing their first pregnancy a month later.

She celebrated her special day with photos of herself and the father-to-be at a light art installation, where he cradled her baby bump. "Thirty-four looks like you & me to infinity," Daisy wrote in the caption.

"Happy birthday my favourite human, sexy baby muma & love of my life @daisylowe," Saul captioned his own birthday tribute, sharing throwback photos of the two of them.

Daisy's half-brother, Kingston Rossdale, 16½, also celebrated the birthday girl with a photo on his Instagram Story of himself and the happy couple getting ice cream.

"Happy birthday!! I hope all your wishes come true! Can't wait to see you again. Love you loads," he wrote with the snap. King Rossdale/Instagram King Rossdale/Instagram

"Wish I was eating ice cream with you @kingrossdale_," Daisy wrote in response.

Rossdale, who shares sons Kingston, Zuma Nesta Rock, 14, and 8½-year-old Apollo Bowie Flynn with ex-wife Gwen Stefani, previously managed to gather all four of his children to celebrate Daisy's birthday last January.

Her mom is British singer/songwriter and fashion designer Pearl Lowe. A 2004 paternity test confirmed Rossdale as her father.
