Watch: Jayson Tatum's girlfriend Ella Mai spotted with apparent baby bump amid Celtics' championship celebrations

On Monday night, Jayson Tatum won the first championship of his NBA career. Among those out to celebrate with him was his girlfriend, and her appearance has the internet buzzing.

According to reports, Tatum began dating singer Ella Mai back in 2020. However, the duo didn't make their relationship public until two years later. Now, it appears the couple could be gearing up for a new adventure together.

Jayson Tatum's girlfriend was spotted out celebrating the Celtics' win, donning his jersey. What stood out the most is that she appeared to have a baby bump. At the time this is being written, the couple has not announced that they are expecting a child.

Ella Mai is from England and has seen success in her own career. The singer/ songwriter first burst on to the scene in 2018 with hit songs "Boo'd Up" and "Trip." The first track would go on to win her a Grammy.

Ella Mai has released three albums since 2016. The latest, "Heart On My Sleeve," came out in 2022. On Spotify alone, the English artiste has over six million monthly listeners.

Jayson Tatum's girlfriend joined Boston Celtics star at teammate's wedding

While they have kept their relationship private for the most part, Jayson Tatum's girlfriend has accompanied him to some big events. One of them being the wedding of one of his former teammates last year.

After spending the first nine years of his career with the Boston Celtics, Marcus Smart was traded last offseason for Kristaps Porzingis. When he and his wife decided to get married, a handful of Celtics were in attendance. Among those being Jayson Tatum and Ella Mai.

This was a big event, but it wasn't the first time Jayson Tatum's girlfriend was spotted with the star forward. The first time they were spotted in public was in 2022 during Michael Rubin's famous White Party that he holds every summer.

After years of coming up just short, Tatum has finally been able to establish himself as a champion. Based on the recent footage, it appears things are working out well for him outside of basketball as well. Coming off a title win with the Celtics, Tatum might be celebrating a lot more this summer.

If Ella Mai is indeed pregnant, Tatum will be becoming a father for the second time. As most know, he has a seven-year-old son named Deuce. He is regularly seen courtside and in the Celtics locker room before and after games.
