When a guy says your lips look shiny, is that compliment?

I knew this guy, he was my friend's ex boyfriend, but we were all still friends. But everyone always thought he had a thing for me. He once said to me "Your lips are really shiny." I had lip gloss on but he didn't know that. Is it a compliment or was he just being observant? Or was he being weird?
