Nina Agdal goes on a dog walk while her friend Jack Brinkley-Cook rides his bicycle in New York

Danish model Nina Agdal rocked an oversized blazer on a dog walk with her boyfriend, Jack Brinkley-Cook, for her 29th birthday on Friday.

While her boyfriend, 25, rode his bike around Central Park in full cycling gear, the Maxim cover girl held her Puggle, Daisy, and a fluffy white pup.

As she prepared to celebrate another year of her life, Agdal wore pink leggings, a flannel shirt, sneakers and a trendy button bun.

Both she and model Christie Brinkley’s son enjoyed some fresh air, but also provided face masks during the ongoing COVID-19 pandemic.

At one point, the lovebirds pulled up to ask an NYPD officer for directions on one of their phones and he was glad he did.

The pair then left the park and Jack loaded his bike into the back of a waiting SUV.
