Kim Kardashian and boyfriend Kanye West just spent a vacation in Brazil,  but before their stay came to an end, they ran in to some friends along the way - Will Smith and Duane Martin.

According to MTV.com, Smith and Martin were also spotted in Rio with the first time parents-to-be, with Will and Kanye spending some time in the studio before they all did some sightseeing together.

The four celebrities seem to have enjoyed their time in the festive city, snapped shots along the way, and also toured some of the city's towns. While Will and Duane are in Brazil for the party that will run until Fat Tuesday, Kardashian and West were reportedly considering purchasing a mansion in the country.  

The reality tv actress had been dealing with some pregnancy issues in the past week. TMZ reported that that the 32-year-old television star was having severe pains relating to her pregnacy last week. She phoned her doctor in the late hours of the night to come to the house. After careful examination, the doctor determined the problems were most likely stress-related. The doctor told Kim that if she did not handle the stress, there could be "long-term'" effects.

Kris Jenner, appeared on ABC's The View, and confirmed her daughter had been indeed seriously suffering from the on-going divorce battle.

"Kim has been going through this divorce. She has been under a lot of stress because of it," Jenner said. "She had a bad week. The doctors told her the stress is going to be a problem."

Seems as if Kardashian is feeling better, and although she did not attend the Grammy Awards with Kanye, she congratulated her boyfriend for winning three awards: Best Rap Performance, Best Rap/Sung Collaboration and Best Rap Song. 

She tweeted, "Awww just waking up in Brazil, seeing Kanye won 3 Grammy's last night!!! That makes a total of 21!!!! That's just so insane! Soooo proud!!!"

The 32-year-old then went on to pick Jennifer Lopez as her favorite look from the night, tweeting: "Wow @JLO looks the best hands down!!! So sexy!!!!"
