'Unpretty Rapstar' Jessi appeared on the March 31 edition of tvN's 'Taxi', so one of her closest celebrity friends, Girls' Generation's Tiffany, joined her for coffee and dessert on the show so they could chat and make people envy their cute friendship.  The two had even uploaded pictures together recently from the day this was filmed.

Tiffany said, "As soon as I came to South Korea, we went to school together from my third year in middle school all through high school.  She's a friend who's fun to be with even without talking."

The two then conversed, mixing in Korean with English.  Tiffany said, "The juniors followed you, saying, 'This is not a competition,'" causing laughter.

Tiffany told Jessi, "On SNS, I saw that you put the hashtag 'Strong Aura Unnie' on your picture," to which Jessi replied, "I don't know why I did that.  You know very well that I was of a hip hop style since I was young."

Tiffany said, "When I see you, I feel proud.  I feel like I'm looking at family.  I got teary because of your words not too long ago, 'I'm proud of us for still doing music,'" and seemed to get teary again.
