(Cover) - EN Showbiz - Lady Gaga celebrated her first anniversary with her boyfriend by eating oysters and caviar.

The songstress and Taylor Kinney have kept their romance largely private since it was revealed that they were dating last year.

However, the stars were happy to openly mark their first anniversary together at upmarket Chicago eatery Spiaggia on Sunday.

According to the New York Post, Gaga and Taylor were accompanied by four friends as they "dined on oysters and caviar to mark the occasion".

Taylor, who is famed for his role in Vampire Diaries, is in the city filming upcoming drama Chicago Fire. Gaga has made "several visits there to see him" since he started shooting the NBC series.

Meanwhile, the international superstar has posted a sultry picture of her and Taylor on her website LittleMonsters.com. Captioned 'T and Me', the snap shows the pair in a seemingly naked embrace in the water.

Gaga and Taylor met on the set of her Yo and I music promo last year. They reportedly split briefly earlier this year, before deciding to give their relationship another go. (C) Cover Media
