Jennifer Aniston just made things official-official with Jim Curtis by showing up at his sold-out book event in Summerland! She rocked her natural grey roots and looked super chill in a green sweater and jeans. Fans are buzzing about how she’s not hiding their romance anymore, especially after going IG official last month. Plus, Jerry Seinfeld and Portia De Rossi were there too! Are we about to see Jenn in full supportive girlfriend mode? #Entertainment #Books #JenniferAniston
