Danica Patrick went into her final NASCAR race ever with a good luck smooch from Aaron Rodgers ... and while the event might be her personal finale, this pic might be a debut.
TMZ Sports has obtained a photo of the new couple giving each other a kiss ahead of Danica's last NASCAR race of her career -- the 2018 Daytona 500. After this, she's retiring.
Eyewitnesses tell us Aaron and Danica puckered up right after the National Anthem ended, before she got into her car at the starting line.
