Stefon Diggs surprised his pregnant girlfriend, Cardi B, at her album release party after news surfaced that he was hit with a paternity lawsuit.

The NFL star was spotted at the rapper’s Apple Music listening bash for her new album “Am I the Drama?” at the Highlight Room in New York City Thursday night.

Diggs celebrated Cardi’s musical success by arriving with a larger-than-life bouquet of Venus Le Fleur red roses in a vase decorated with images of her face.

Cardi, 32, looked surprised as she hugged Diggs, 31, while wearing a robe and slippers.

The “WAP” rapper clearly had a good time as she was seen exiting the soirée after 3 a.m. while showing off her growing baby bump in a lace ensemble draped in pearls.

The fête came just two days after Cardi announced that she is pregnant and expecting her first child with the athlete.

“I’m excited, I’m happy, I feel like I’m in a good space,” she told Gayle King on “CBS Mornings” Wednesday.

Cardi — who already shares three kids with estranged husband Offset — confirmed that she is due before her tour kicks off in February.

She also explained why she waited to confirm the pregnancy news amid rumors that she was having another baby.

“I felt like, ‘Can I just say it on my own time?’ I’m not hiding,” she said.

The next day, Page Six reported that Diggs was accused of fathering a child with Aileen Lopera.

Lopera claimed in documents filed in December 2024 that Diggs was the “parent” of her child, Charliee Harper Diggs-Lopera, who was born on April 2.

However, the NFL star questioned his paternity, saying that he was “not certain” he was the child’s father and requested a genetic test.

Cardi and Diggs took their romance public in May when they looked loved-up while attending an NBA game on May 12.

One day prior, Diggs was spotted outside of a New York City hospital holding a baby carrier while joined by an unknown woman. Lopera’s lawyer confirmed that the woman seen with Diggs was not her client.

“I can confirm that is not my client in the video and no car seat has been provided to her,” Lopera’s attorney, Tamar Arminak, told Page Six on Sept. 19. 

“My client looks forward to the day Mr. Diggs finally meets, acknowledges and provides for the infant daughter they share,” the attorney added. Page Six has reached out to the New England Patriots star’s reps for comment.
