Arkadiusz Milik Wife? Agata Sieramska Is His Partner

Arkadiusz Milik is not reported to be married. His long-time partner is Agata Sieramska, a Polish model and fitness influencer who is known on Instagram as @agata.sieramska. We found no report of a wedding or an engagement, so this article calls her his partner rather than his wife. Milik is a Polish striker who, as of November 2026, is still under contract with Juventus until 30 June 2027.

This page covers who Sieramska is, what is publicly documented about the couple, and where Milik's career stands after years of serious injuries. We only use facts that Polish and Italian media or the two of them have published themselves. Where nothing has been published (her parents, her education, her birth year, any children), we say so.

Who is Arkadiusz Milik's partner?

Agata Sieramska is a Polish influencer who posts about sport, healthy living, diet and fashion, according to Polish sports site Sportowe Fakty. She is described in Polish and Italian media as a model and fitness influencer. She and Milik are described as a well-known couple "for years" by Sportowe Fakty, but neither of them has published a date for when it began.

Some older profiles give late 2021 as the start of the relationship and February 2022 as the moment it went public. We could not confirm either date from a reliable source, so we leave them out. The earliest dated evidence we found is from September 2022, listed below.

If you came here searching in Italian for "fidanzata di Milik" or "moglie di Milik": the Italian press calls Sieramska his fidanzata (partner), and no marriage has been reported.

The couple: what is documented

September 2022: Milik posted a photo of the interior of a new home in Turin with a caption that read "Wreszcie w nowym domu z moją Agatą", meaning finally in a new home with my Agata. Sieramska shared a terrace photo of the same home, reported by Super Express on 18 September 2022.
January 2024: After Milik scored a hat-trick for Juventus against Frosinone in the Coppa Italia (11 January 2024), Sieramska, who watched from the stands, posted a video of the goals. Her caption, according to Super Express, was "Mega dumna Arek. Forza Juve!", which means very proud of Arek.
10 June 2026: Sportowe Fakty reported that Milik posted a joint photo on Instagram for her 32nd birthday, with the caption "Wszystkiego najlepszego Amore" (happy birthday, my love).

We found no report of an engagement, a wedding or a break-up. As far as is publicly known, they are still together as of November 2026, but the most recent evidence we found is the June 2026 birthday post.

Does Arkadiusz Milik have children?

We found no report that Milik and Sieramska have children, and no mention of children in the sources above. Both keep the details of their private life off the record, and we do not guess.

Milik's earlier engagement

English Wikipedia says Milik was in a relationship with Polish model Jessica Ziółek from 2013, and that they called off their engagement in late 2020. Neither has said more publicly in the sources we checked, so we do not add anything else about it.

What does Agata Sieramska do for work?

Her work is on Instagram. Her account mixes workouts, healthy-living tips, fashion and everyday life, and Polish media regularly cover it in their celebrity sections. We could not find a published interview with her that explains her career in her own words, so we do not describe her business, brand deals or income beyond what is visible on her own page.

Injuries

Milik's career has been shaped by injuries, according to English Wikipedia:

A torn anterior cruciate ligament in a Poland match against Denmark on 8 October 2016.
A second cruciate injury, in the other knee, in September 2017.
Missed UEFA Euro 2020 through injury.
A knee injury about 80 seconds into a Poland friendly against Ukraine on 7 June 2024, which ruled him out of Euro 2024.
Meniscus surgery in June 2024, after which he missed the whole 2024/25 season and most of 2025/26.

In 2025/26, English Wikipedia counts two Serie A appearances and no goals for him. Rotowire logged a calf problem in March 2026, and Juventus announced a moderate biceps femoris tear in his right thigh on 15 April 2026. He was an unused substitute in the 2-0 defeat to Fiorentina on 17 May 2026.

Where Milik plays in 2026/27

Milik is still a Juventus player in the 2026/27 season: Juventus extended his contract to 30 June 2027 in April 2025, and the club's announcement is public. But early September 2026 reports, citing journalist Romeo Agresti, said that Juventus had left him out of their Serie A and Europa League squad lists. In April 2026, after his thigh injury, Tuttosport had reported that he and Juventus were expected to end his contract by mutual agreement at the end of 2025/26. As of November 2026 we found no confirmed departure and no new club.

Juventus' official highlights of the 4-0 win over Frosinone on 11 January 2024 show the hat-trick that Sieramska celebrated online: Milik scored in the 11th, 38th and 48th minutes, and Kenan Yildiz also scored.
