The model mom showed off her growing baby bump during a trip to the beach on Sunday, October 4, announcing her BIG news.
"Sorry we can’t hang out, there’s a pandemic & I’m pregnant ... again. ?We love consistency!" she wrote.
The baby, who is due in December, will join their ever-growing family, which includes daughters Lola, 19 months, and Mia, 2, plus the singer's 10-year-old son Julian, whom he shares with ex-wife Paula Patton.
Thicke, 43, and Geary, 25, got engaged on Christmas Eve 2018 — two months before Lola was born. Thicke and Geary started dating in the months following his separation from Patton in February 2014.
After six years together, their love gets stronger and stronger.
"Omg SIX years, two babies, one burned down house and one less appendix between us ?," Geary wrote on Instagram in September. "I love you so much and I couldn't imagine my life without you."
"You're the best father, partner, cook, lover! I know I'm rarely ever romantic or serious (lol) but you're truly my other half and you love me more than anyone ever has before," Geary added. "Forever & always ♥️ @robinthicke."
The road to a happy family, however, hasn't been without pain and heartbreak — Geary had a miscarriage in 2017 before she gave birth to their daughter Mia in February 2018.
Well, it seems like everything worked out for the best. Congrats to the happy couple!
