Mass Effect 2 Kelly Chambers Cabin Invite

@Mrgaby95 @dylan881 Problem solved itself on a new run and this is what I did different: I still recruited everyone (Zaeed and Kasumi plus their two loyalty missions) prior to Horizon and talked to her "How's the Crew" everytime (even after some side missions), did Horizon talked to her, did Jacob loyalty and talked with her, did Miranda loyalty and talked to her, recruited the second round of recruits and talked to her (yes the last three dossiers were available before Collector Ship), then the Collector ship mission and when I went to talk to her the option to "Ah you do care" popped up which rather than a hug lead to the friendly dinner and yes she took care of the fishes.
Keep in mind I acquired the non DLC crew loyalty missions, minus Thane which hasn't triggered yet, through her first rather than finding out when talking to them. I chose "I'd catch you" in the first meeting just in case. Now let's see if Thane loyalty mission pops up as Kelly told me Tali got a very important message (which the trial will have to wait until after the Reaper).
