One of the most talked-about appearances involved Jennifer Aniston in 2006 while promoting the film The Break-Up. Much of the segment focused on comments about her appearance rather than her work, with repeated attention directed toward her legs and personal life, creating a moment that many viewers today see as uncomfortable.
An earlier 1998 interview resurfaced online as well, when Letterman unexpectedly placed a strand of Aniston’s hair in his mouth during the conversation. Although the audience laughed at the time, the moment has since been widely reexamined as an example of how personal boundaries for female guests were sometimes overlooked in entertainment.
Despite those awkward moments, Aniston handled the situations with composure and continued appearing on the show. During a later visit promoting Marley & Me, she shifted the tone by humorously presenting Letterman with a tie she had worn on a GQ cover, demonstrating her ability to redirect the conversation and maintain control of the moment.
