The Fancy star was first linked to the rapper in June (16) when they were pictured partying in Las Vegas and fuelled the speculation again in August (16) after they were seen kissing on a yacht in Cabo San Lucas, Mexico.
However, she continued to deny they were an item when asked by reporters at Los Angeles airport in September (16), insisting she was still single and they were "just friends".
Her latest Instagram post seems to suggest otherwise, as it appears French has treated his new lady to seven diamond rings. In the snap of her ring hand, the seven bands, filled with diamonds, are spread across three fingers.
"He told me pressure makes diamonds," she wrote in the caption, referring to the quote made by U.S. General George S. Patton who lead American troops during World War I and World War II, which was subsequently used as the title of a Don Williams song.
She also tagged French in the caption after a love heart emoji and a jeweller who goes by the handle Iceman Nick.
This isn't the first lot of diamond rings Iggy has been gifted - she was given a sparkler by former fiance Nick Young in June, 2015, but a year later the engagement was called off after Iggy allegedly caught him being unfaithful in their home.
"I broke up with Nick because I found out he had brought other women into our home while I was away and caught them on the security footage," she tweeted in June (16). "This is just like a second shot to the chest. I feel like I don't even know who the hell it is I've been loving all this time. People in this world really are f**ked up."
French previously dated reality TV star Khloe Kardashian.
