Lady Gaga and Taylor Kinney celebrated their first anniversary with a dinner of oysters and caviar.

The 'Born This Way' singer and the 'Vampire Diaries' hunk went for a meal at Chicago restaurant Spiaggia on Sunday to mark the special date.

The couple were joined by four friends for the seafood feast, according to the New York Post newspaper.

Taylor, 31, has been in the city filming upcoming NBC drama 'Chicago Fire' and Gaga has made regular visits to Chicago to see her man.

The pair met filming the video to her single 'You and I' in July 2011 and started dating just a couple of weeks later.

The couple did briefly split in May due to the pop superstar's touring commitments but they soon reconciled and are now closer than ever. 

Meanwhile, Gaga is to make her acting debut in 'Machete Kills'.

The 26-year-old star has joined the cast of Robert Rodriguez's action movie - a follow up to 2010's 'Machete' - and will play La Chameleon in the film.

She wrote on her twitter page: "Yes its true, I will be making my debut as an actress ln the amazing MACHETE KILLS BY @RODRIGUEZ IM SO EXCITED!!! AH! Filming was insane. (sic)"
