The on-again, off-again relationship between Rob Gronkowski and Camille Kostek appears, well, on again.

The Patriots tight end and the ex-cheerleader have been linked to each other for over a year, but reports surfaced that they split up earlier this year. Gronkowski has proceeded to have a whirlwind offseason that would make most men jealous, but perhaps Kostek isn't out of his life after all.

Gronkowski and Kostek were spotted out and about together in a photo that surfaced on Instagram. While it didn't confirm their romance being rekindled, the picture of both of them hanging out has led to rumors they are once again a couple.

When word first broke about the split between Gronkowski and Kostek in January, it was believed the four-time Pro Bowler called it off with Kostek to focus on a high school flame. There were also rumors that the tight end viewed the beautiful blonde model as his "side girl," not his actual girlfriend.

Their relationship has been very murky, as in February, Gronkowski and Kostek were spotted on a date together chowing down on some sushi. Whatever their relationship status is, Gronkowski hasn't stopped having fun this offseason.

Not only did the tight end host his very own booze cruise, the Patriots star has also had an A-list celebrity publicly reveal her crush on him this offseason, while an on-air sports anchor requested his services for a controversial lap dance.

Gronkowski, who recently went on a photo shoot with beautiful models, has been seen with many women this offseason, which may lay credence to the speculation of Kostek being his "side girl."

Last month, he was spotted leaving a Los Angeles nightclub with a blonde bombshell and prior to that, he boarded a private jet to Florida flanked by gorgeous models en route to Ultra Fest in Miami. He was also seen on Snapchat hanging out with beautiful Instagram model Rachel Bush.

The Patriots fell to the eventual Super Bowl champion Broncos, 20-18, in the AFC Championship Game in January, failing in their quest to get back to the Super Bowl for a second straight season. Gronkowski had 72 receptions for 1,176 yards with 11 touchdowns as he helped lead New England to its seventh straight AFC East title in 2015.

His offseason, however, has been even better -- and he may even be rekindling his romance with Kostek.
