Queen Elizabeth met her great-granddaughter for the first time over the weekend, but don't expect to see QE on any pages of Lilibet's baby book ... because she reportedly banned photos from being taken of the introduction.
The report states Harry and Meghan were informed the intro would only be a private family meeting -- and there was a worry if photos were taken, they'd be passed around in America.
There was certainly a lot of tension between Harry and his family through the weekend as evidenced early on -- the photo above shows Prince William and Harry on opposite sides of the church during the National Service of Thanksgiving.
Harry and Meghan didn't stick around for the celebration's closing, either ... the Sussexes and their 2 children flew private from London to Cali. Of course, if they stayed, it's unlikely they'd have been allowed to stand beside the Queen when she appeared Sunday on her Buckingham Palace balcony.
We've reached out to Harry and Meghan's reps for comment ... so far, no word back.
