Though things appear to be just fine in Michelle Rodriguez and Cara Delevingne's relationship, the model may be hinting that she is ready to move on with someone else.

Cara Delevingne Cheats on Michelle Rodriguez With Sienna Miller?

The 21-year-old, who was spotted out with actress Sienna Miller in London last week, was caught arriving at JFK airport in New York May 3, and told TMZ about the nickname she has for the actress.

"She's my Schnoyster," Delevingne said. "We're very much 'schnoistering.' Yes, that [nickname] is already trademarked. We share that much in common."

Michelle Rodrgiuez Jealous of Cara Delevingne's Friendship with Suki Waterhouse?

The model didn't offer an explanation on what the nickname meant, but did seem to find the rumors she was dating Miller funny, laughing and commenting that it was funny.

She and Miller were spotted together twice last week, as rumors continued to swirl that she and Rodriguez had split because of hardly being able to spend time together with the model's busy work schedule.

Miller and Delevingne were spotted leaving Mayfair club in London while holding hands, and also posed together at Kate Moss's Top Shop party.

The two were also spotted kissing at last year's Met Ball, in a photo the model posted on her Instagram page at the time.

Delevingne isn't the only one who has assigned a nickname to someone. Her BFF and fellow model Suki Waterhouse referred to her as Shugapoo in her own April Instagram post, which showed the two models snuggled up in bed together.

Rodriguez, who has been in L.A. while her girlfriend has been jetting around the world, appeared to be putting the rumors of a break-up to rest last week by tweeting about a future movie project that she reportedly wanted to take on with Delevingne as her co-star.
