Why is my husband meeting up with women to "network"?

My husband is very successful executive at a large company and many people contact him on linkedin or by email for professional purposes. He recently told me he's having lunch with some woman that recently moved to the city, that is working at his former company (also a large company) and she messaged him on Linkedin asking for advice. I looked her up and she is VERY pretty. Like a model or something. I don't get why he needs to meet her in person for lunch and not over zoom? She isn't at his current company. He gets nothing out of this - just helping some beautiful woman with no friends in town? I feel uncomfortable about it. He meets loads of people on zoom - never heard of him going to lunch with someone he doesn't know but he did tell me about it. Should I say something? Is it normal or am I being insecure?
