The 28-year-old "Friends with Benefits" actress jumped into a swimming pool and wrapped herself in a towel after climbing out. Kutcher later approached the brunette beauty, giving her an affectionate hug and kiss, reported Ace Showbiz.
A few days ago, the two actors were also seen enjoying a date. They were having lunch together and holding hands.
"Kunis kept running her hands through Kutcher's hair and that Kutcher leaned in to whisper something in Kunis' ear and then he kissed her on the cheek," a source said.
Rumours of a romance between the two have been circling since April of this year but neither of them has admitted that they are dating.
Both stars have recently come out of a serious relationship each. Kutcher split from wife Demi Moore late last year amidst cheating rumors. Kunis, on the other hand, was confirmed in January 2011 that she ended her romance with her boyfriend of eight years, Macaulay Culkin.
