Paparazzi caught the 46-year-old grabbing a big gulp while pumping gas in Los Angeles. They grilled the former beauty queen on what she thought about Travis getting down on one knee in front of reality show cameras.
Shanna appeared to smirk a little after being asked, "Do you have any comment on Travis' engagement to Kourtney?" She continued walking as another shouted out, "Was it a surprise for you as it was for everyone?"
Travis' ex tried to quickly finish topping off the gas to avoid before asking anything else. However, one cameraman was able to get in one final question.
"Would you attend the wedding if you got invited?" he shouted. Shanna looked back at the camera and appeared to laugh at the idea of being at that wedding.
Shanna is not a fan of her ex or the Kardashian family. Back in May, a couple of months after Travis started dating Kourtney, she came forward to bring up old accusations against Kim Kardashian.

She claimed her marriage to Travis ended after she found out he slept with Kim. Shanna said after Travis got with Kourtney earlier this year the kids they share stopped talking to her.
"My family is broken because of this family and now my kids and I are alienated from each other because of another sister in the family, so yay for me," she said at the time.
Travis and Travis were married from 2004 until 2008. They share a 17-year-old son Landon and a 15-year-old daughter named Alabama.
The only indication Shanna gave on Travis getting engaged to Kourtney came with a cryptic Instagram Story quote. She posted, 'Temporarily closed for spiritual maintenance."
