Kylie, who is rumoured to be dating rapper Tyga, was busy running errands when she was discovered by photographers leaving a pharmacy.
The Keeping Up With The Kardashians star, who was dressed head to toe in inconspicuous black, was talking on her phone and trying to hide her face from the paps.
However, the huge gold band she was wearing on her ring finger remained very obvious as she used her left hand to shield her face.
Although the jewellery doesn't look much like an engagement ring to us, could Kylie be sending a message that there really is something going on with Tyga?
The pair were last seen together when they attended French Montana's 30th birthday party this weekend, along with other members of Kylie's family.
Kylie recently spent 12 hours in a Beverly Hills beauty salon while she had grey hair extensions fitted.
