'Modern Family' Star Sarah Hyland Enjoys Major PDA with 'Bachelor' BF

Sarah Hyland and her bf, Wells Adams, had a busy Tuesday ... a little PDA, a little chit chat, and lots of pizza stuffin.

The "Modern Family" star spent the bulk of her Tuesday all over L.A. with the former 'Bachelor' contestant. They got handsy after a lunch date at Joan's on Third ... then went for a stroll and then shopping in Studio City. But there was more.

Sarah and Wells hit up the Lakers game in the evening and stuffed their faces with pizza. Bonus: the Lakers roared back to beat the Bulls.

All's well that ends ... with Wells.
