KARA's Goo Hara is all smiles for her birthday as she shows off a very special birthday cake.

International sportswear brand Adidas helped the KARA member celebrate her birthday this year with a special cake designed with the company logo.

The 23-year-old singer and actress celebrated her special day on January 13 and the festivities included the special treat from Adidas.

Hara updated her Twitter with a picture of herself holding the tasty present and the message, "Thank you Adidas."

Hara joined popular K-Pop girl group KARA back in 2008 after the departure of member Sunghee and was a part of the group when they achieved their first number one single "Honey" in February 2009.

She has dabbled in acting in addition to her musical pursuits and has appeared in a range of variety shows and dramas in the past six years including playing the role of the President's daughter in Lee Min Ho's popular series City Hunter. Hara has also been host and MC for several music programs and awards shows over the years.

With the recent news that Hara's fellow KARA member Nicole will be exiting the group next month after the end of her contract with their agency DSP Media on Thursday, the fate of the pop group is in the air.

But one thing is for sure, Hara enjoyed her birthday this week, especially her personalized cake from Adidas!
