I can’t verify that specific behind-the-scenes quote from the available information, so I shouldn’t invent what Anne Hathaway said. The public results I found only confirm general Princess Diaries and Valentine’s Day materials, not a reliable source for that exact lipstick-on-set story.

What can be said safely

  • Anne Hathaway and Topher Grace did appear together in Valentine’s Day , which is the most likely context for public interview or behind-the-scenes stories involving them.
  • I found no trustworthy source here that confirms a direct quote about a kiss, shiny pink lipstick, or a Princess Diaries set visit.
  • The lip/color references in the search results point to makeup commentary about The Princess Diaries , but not to the boyfriend story you asked about.

Best answer

  • Unknown / unverified.
  • If this is a viral forum claim, it should be treated as gossip unless a primary interview or behind-the-scenes clip surfaces.

TL;DR

There isn’t enough verified evidence here to state what Anne Hathaway allegedly said, so the safest answer is that the quote is unconfirmed.
