Awkward situation with one of FHs guests. Unsure how to proceed.

So while we were in university one of my FHs groomsmen who was my roommate for 4 years (let's call him R) dated a girl we will call K. K and I never really got along but FH and K were very close in university. When K and R broke up, K kind of phased out of our friend group. Fh and K still talk occasionally mostly via text and sometimes he goes In to her place of work for professional advice. We were guests at her wedding last year and her and her husband will be coming as guests to our wedding. Like I said we never really got along super well, i was and still am quite close to R and had no real reason to keep in touch with k, but we are in no way on bad terms. This morning she texted me (I had no clue who it was as i don't even have her number, no idea how she got mine) asking if anyone was planning my shower/stagette. I replied that yes I have 4 bridesmaids planning one of which has kindly taken the lead in planning to which she replied asking if she could contact my bridesmaid to see if she could help plan? Is it just me or is this super weird? I wouldn't even consider us friends honestly, she's my fiances friend who I never talk to. I wasn't invited to her shower or stagette and I certainly wasn't involved in any planning. I'm a little off put that she feels like she should be planning my shower. The really awkward bit is that I wasn't planning on inviting her to my shower or stagette. Now I feel extremely awkward. Not really sure what to do. Should I be inviting her? I'm very confused.

TLDR; FHs university friend who I was never close with asked me if she could reach out to my bridesmaids to see if she could help plan stagette/shower. I wasn't planning on inviting her to either event as we aren't close at all. Unsure if I should be inviting her.
