Tammy Hembrow has ignited speculation about a potential engagement to her boyfriend, Grayson Te Moana, following a public display of affection at Sydney Airport. The 32-year-old influencer and the 23-year-old model were seen sharing a passionate kiss while awaiting their flight to Adelaide.

Hembrow, dressed in a sporty-chic tracksuit, and Te Moana, in a casual hoodie and sweatpants, appeared engrossed in each other as they waited at the departure gate.

When questioned by the Daily Mail about whether an engagement was on the horizon, Hembrow offered a succinct and teasing response: "maybe." The couple was later observed walking through the terminal, with Te Moana, who is significantly taller than Hembrow, accompanying her and their luggage.

Their trip to South Australia was also met with a playful deflection from Hembrow, who jokingly called it a "surprise." This outing follows a recent instance where Te Moana shared a social media post that appeared to joke about Hembrow being pregnant. He posted a screenshot of Hembrow filling out a waiver form that included a question about pregnancy, with Hembrow seemingly indicating she was in her first trimester. Te Moana quickly clarified the post with the caption "Fun waiver joke," but it did little to quell fan curiosity.

Hembrow has three children from previous relationships: son Wolf, 11, and daughter Saskia, 9, with ex-fiancé Reece Hawkins, and daughter Posy, 4, with ex-fiancé Matt Poole. Her current relationship with Te Moana has been a focus since they were first seen together in March on the Gold Coast, shortly after publicly confirming their relationship. They made their romance public at the Australian premiere of "Wuthering Heights" in Sydney in February. Te Moana is the latest in a series of high-profile relationships for Hembrow, including a past relationship with AFL player Bailey Smith.
