Olivia Culpo and Danny Amendola's kissing reportedly led to complaints from fellow diners at a restaurant in Rhode Island.
The 26-year-old model - who previously dated Nick Jonas - was happy to display her affection for her NFL star beau in a very public way, but their intense smooching prompted the folks sat on the table next to them to complain to the management.
An eyewitness told the New York Post newspaper's Page Six column that the loved-up couple were "having a hot make-out session" as they sat with pals at Scarpetta at Gurney's restaurant.
However, the management is not thought to have raised the issue with the celebrity duo.
Last month, a source close to the pair claimed that Olivia and Danny were still "working on their relationship".
The former Miss Universe initially sparked rumours that she'd rekindled her romance with the 32-year-old sports star earlier in June when he invited her to a wedding in Houston as his date.
But friends subsequently claimed they were not officially an item and that they were still trying to work through the issues that caused them to separate in March.
The insider explained: "Olivia and Danny are not exclusively dating, but are working on their relationship. Danny reached out to Olivia and wanted to clear the air between them. She had previously told him she would be his date to a wedding, and decided to go with him last weekend."
The source claimed Olivia has "minor commitment issues", while their jam-packed working schedules also make it difficult for them to maintain a healthy relationship.
The insider shared: "They are working on things and are definitely talking and seeing each other often. Olivia has minor commitment issues and is very independent, making it hard for her to be in a relationship.
"She also travels often and is very busy with work, which is hard."
