In one photo she placed cartoon flames over her bottom with the caption: ‘How I feel’. 

Earlier in the week the Modern Family actress had slid on a pair of loose-fitting jeans that featured a tear at her upper thigh.

Facing away from the camera but peering at it over her shoulder, Ariel modeled a sleeveless white high-cut crop top.

She was outside on a sunlit sidewalk in the photo, which was part of an album.

The other snapshot in the album appeared to be a version of the first photo, just stylized to become multiple layers of the same image.

Ariel has been playing the acerbic Alex Dunphy on the hit ABC sitcom Modern Family since its pilot episode premiered on the network back in 2009.

Last month, Ariel’s co-star Sofia Vergara once again took the top position on the Forbes list of the highest-earning television actresses on the planet.

The period being looked at was June 1 last year to the same date this year. Sofia’s now held onto the number one spot for six years running.

While not working on her smash show, Ariel’s busy personal life includes a relationship with her live-in boyfriend Levi Meaden, who incidentally is 29.

Ariel chatted to Refinery29 this year and said of her romance with Levi, with its decade-wide age gap: ‘I’m happy, and whatever people want to say, they can say.’

Said she: ‘I don’t understand why someone would even comment on our situation at all. There are tons of people of all ages that live with their boyfriend.’

Conversely, as she’s noted, ‘There are tons of people that live with their girlfriends, [and] tons of people that don’t live together and are super happy. But I’m super happy in the arrangement that we have. We love living together. It’s just great.’

The teenager rhapsodized: ‘I have to say he is the most incredible person I’ve ever met and that I’m so lucky to be with him. He’s always complimenting me and making me feel special and beautiful,’ she confided.

‘We went grocery shopping today, and I was in, like, a weird T-shirt that I kind of hate and my semi-pajama pants, and he still took the time to tell me that I look pretty.’
