The outing comes just days after the former backup dancer celebrated the New Year with all her kids and fiance by her side.

Jennifer and the former pro baseball player rung in the new year with their combined four children and even shared a midnight kiss.

In a video Alex posted on Instagram, the family were seen counting down into the new year before the engaged parents packed on the PDA.

‘Happy New Year 2020,’ he captioned.

Alex, who looked very dapper, also took to his Stories to wish his fans – even encouraging them to partake in lots of drinking and smoking to wrap up the decade.
