Tamra sent some big birthday wishes to Spencer, who she "can't believe" is 17 now, on Instagram Wednesday with one of her favorite photos of her son. "Sums up his personality 'Quiet & serious.' (I think it's the only selfie he's ever taken)," Tamra explained in the caption to the pic. "Everyone tells him he should be a model but he would rather talk politics and world history."
If you're amazed by how much Tamra's children have grown up right before your very eyes, you're not the only one. "Spencer is a junior in high school and driving and Sophia just started middle school," Tamra updated RHOC fans in her Bravotv.com last August. "I can't believe it's been eight years since they have been seen on the show."
