We kinda don't blame her ... Hailey Baldwin's not usually so shy in front of the paparazzi but today, during an outing with pal and fellow supermodel Kendall Jenner she literally did everything she could to avoid their lenses.

Hails even had Kendall drive hubby Justin Bieber's $250K Lamborghini Urus SUV as they left a Beverly Hills spa following some chillaxing girl time.

Our videographer kind of yelled out to Hailey, asking her if she's worried Justin will actually end up fighting Tom Cruise -- after her hubby issued the very odd and questionable challenge to the iconic 56-year-old Mission Impossible star. So we assume the headlines surrounding Justin's random Tweet are putting Baldwin in an uncomfortable position, being asked questions like ours.

And in the past two days since Justin had this bizarre idea and Tweeted it out to the world, of course Mr. Cruise has not answered. So could this fight even happen? The guys at SBD say the odds the fight actually happens are really slim. They have even less optimism for Conor McGregor vs Mark Wahlberg -- another random challenge that was issued by McGregor who also says he'll host at promote Bieber vs. Cruise.

Some oddsmakers actually call Bieber as the winner ... what do YOU think?!
