El Moussa shared a photo with his wife, Heather, who is pregnant with their first child together, and his son, 7-year-old Brayden, who he shares with ex-wife Christina Hall. "Like many of you out there, today we dropped the little man off to first grade!" he wrote. "Life is a wild ride and it's crazy how time flies! I feel like yesterday my little guy was in nappies throwing food off his tray:) well . . . he's out of the nappies but still throwing food lol. I'm having so much fun watching him change and grow. In the last two weeks he drove go carts, went body boarding, and had his first football practice!! This is just the best age and we are having so much fun! I can't tell you how much I love being this kids dad!❤️"
