On Tuesday (11May21), the Blink-182 drummer shared a photo of Goop's famous "This Smells Like My Orgasm" candle - only his version incorporated a lustful reference to the "Keeping Up with the Kardashians" star on its label.
The candle's label reads, "This Smells Like Kourtney's Orgasm", a play on the $75 (£53) "This Smells Like My Orgasm" votive created by Gwyneth Paltrow's lifestyle brand Goop and Heretic perfumer Douglas Little.
While Barker didn't add a caption to the post on his Instagram Story, his girlfriend appreciated the tribute and reshared the post on her own account.
"This Smells Like My Orgasm" was released last year as a follow-up to the "This Smells Like My Vagina" candle, which quickly sold out.
The celebrity duo sparked romance rumours after they both posted social media snaps from Kris Jenner's Palm Springs home before making their romance Instagram official with an intimate photo in February showing her hand intertwined with her drummer beau's.
Before dating Travis Barker, Kourtney was in an on-and-off relationship with Scott Disick and then Younes Bendjima. She shares three children with Scott and the two sparked reconciliation rumors and even baby rumors before she went public with Travis.
Meanwhile, Travis was previously married to Melissa Kennedy and then to Shanna Moakler. He shares two children with Shanna. He once dated Rita Ora, who's coincidentally Rob Kardashian's former girlfriend.
