Stacey Solomon's rarely seen ex, and dad to her eldest son Zachary, appeared on her family reality show Stacey & Joe for the first time on Tuesday night. Stacey, who was just 18 when she had her first child Zachary in 2007, with childhood sweetheart, Dean, also opened up about facing teenage pregnancy. Zach looked thrilled as his dad and his partner arrived and gave him a huge hug and said: 'Can't believe your 17!' Stacey later gushed, 'We've done alright', and Dean agreed, 'We've smashed it with you'. Step-mum Nikki said: 'When we tell people, we're like, "Oh yeah Dean (pictured) has a 17-year-old son", they go, "What!"
