Khloé Kardashian just wants ''to have fun'' in 2015.

The 30-year-old reality TV star, who filed for divorce from her estranged husband, Lamar Odom, in December 2013 and ended her on-again, off-again relationship with rapper French Montana earlier this month, is happily single and wants to focus on bettering herself.

The 'Keeping Up with the Kardashians' beauty said: ''I think being single is really healthy for people. I think people who go into one relationship to another, I don't know if they have a healing process or know what went wrong or how to better themselves.''

Despite recently suggesting she had moved on with French too quickly and didn't give herself enough time to heal after her marriage ended, Khloé says she has no regrets and had a great year.

She told PEOPLE.com: ''I just want to have fun. Lessons learned? I just want to really enjoy life. I feel like I had a really good 2014. I just want to make 2015 better and better. I just want to win. I just want to win at everything I do.''

Khloé and French were both spotted having dinner at Mirage's Stack restaurant in Las Vegas on Tuesday (30.12.14), where they appeared to be cordial.

But the star recently hinted she regretted dating him, saying: ''I jumped into something because I was just, like, lonely and destructive. But now I'm like, I just want to be alone. I gotta grieve. I'm still married.''
