Liam Payne expressed his jealousy on Friday (28Oct16) as his girlfriend Cheryl mingled with fans in the U.K. while he was working on music in Los Angeles.
The One Direction star has been in the studio preparing his debut solo album, while Cheryl has been keeping busy with her professional commitments in their native England.
On Thursday (27Oct16), Cheryl promoted her new fragrance Storm Flower Platinum at an event in London, and after a successful bash, the ex-Girls Aloud beauty took to her Instagram page to thank fans for the turnout.
"I always love spending the day with you lot!! It makes me so happy. Thank you to everyone who came to the signing today. I loved it," she wrote.
Liam couldn't resist sharing his love for his girlfriend, quickly replying on the social media site: "@CherylOfficial so jealous of everyone who got to spend the day with my girl today grrrrrrr (sic)!"
Fans were quick to show their appreciation for his message, which was retweeted more than 5,000 times and quickly attracted over 10,000 likes.
Cheryl, 33, has been dating Liam, 23, since last December (15), with the pair's relationship appearing to go from strength to strength. Recent reports suggested Cheryl is pregnant with Liam's baby, and the singer did little to dispel the claims at her fragrance event.
The beauty wore an optical illusion blue jumpsuit for the meet-and-greet, which concealed any signs of a bump, and chose to have the bulk of photos taken while sitting behind a table.
According to fans at the event, Cheryl remained seated throughout the signing as she had snaps taken with her dedicated followers.
Several fans also remarked that Cheryl was "glowing" in her Rachel Zoe jumpsuit, which she teamed with straight hair and subtle, bronze make-up.
