Coolio's sudden death comes as a total shock to fans who interacted with him less than a week before he passed, and they say he gave no indication he was having health issues.
TMZ obtained these photos and videos of the "Gangsta's Paradise" rapper traveling last Friday through the Houston airport, and he was happy and in good spirits as he greeted some giddy fans.
Mika, the woman who stopped Coolio in the airport, tells TMZ ... she ran up to him to get a photo and he was friendly and very happy to take some pics, laughing and being very engaging.
We're told he even invited Mika and her girl pals to come to his show that night in Cypress, TX and they exchanged numbers and text messages -- and Coolio got the women on the VIP guest list.
Coolio's Last Performance Was With Vanilla Ice, Ice Remembers His Friend
Mika says she and her friends didn't end up going to the show because it was about an hour from where they were staying in Houston, and now they're devastated they missed that chance to see what turned out to be his last live performance.
TMZ broke the story ... Coolio died Wednesday afternoon at a friend's house in L.A., and his Friday concert with Vanilla Ice in Texas ended up being his last gig.
Coolio went to the bathroom at his friend's place and never came out ... his friend called 911 and paramedics gave him CPR for 45 minutes in an effort to revive the rapper.
Law enforcement sources say no drugs or drug paraphernalia were found at the scene of his death. An autopsy and toxicology test will be used to determine the official cause of death.
It's no wonder Coolio's friends and fans are shocked -- he seemed to be the picture of good health leading up to his puzzling death.
