It has been rumored that Kim Kardashian's ex, Reggie Bush, is dating Canadian pop-singer and Kardashian look-alike, Melissa Molinaro. Though their resemblance is quite striking, we differentiate between the two women and their careers.

Kim Kardashian

The raven-haired Kardashian, 30, is known for her hit E! Entertainment show, Keeping Up With The Kardashians, where she and her sisters parade around Los Angeles, Las Vegas, and New York, talking about family, work, men, and each other. She was also recently named Glamour's Entrepreneur of the Year at their June 7 award ceremony, at which she was awarded the Glamour Women of the Year Award.

Kardashian shot to reality-star stardom when a sex tape of her and former boyfriend, singer Ray J, surfaced in 2007.

This tape, which was made three years ago, and was meant to be something private between myself and my then-boyfriend is extremely hurtful not only to me, but to my family as well, Kardashian said in a statement to PEOPLE.

Kardashian has had several stints on TV, aside from her E! shows (she is also the star of E!'s 'Kourtney & Kim Take New York'). She was one of the participants on the seventh season of Dancing with the Stars.

She has also starred (alongside Carmen Electra) in the 2008 Disaster Movie, and if you didn't hear of it you're not alone. The film spoofed disaster films, but as it turns out ratings proved the movie to be a disaster in and of itself. On Rotten Tomatoes, the film received a lowly 2 percent from the Tomatometer, and 28 percent from audiences.

Kardashian also had a small role on 'CSI: NY' as Debbie Fallon on the episode Second Chances in 2009. 

Kardashian has also put out a pop song, Jam (Turn It Up), in 2011, which received poor reviews. The reality star told Ryan Seacrest before he played the song, It's only normal for me to be nervous. I'm human, I never sang before. This was definitely something I don't do, so for me to step outside my comfort zone to do this ... is like a really big deal.

As a designer, Kim has her own fragrance, which is self-titled and has the tagline of, 'The Voluptuous New Fragrance.' She has also designed clothing and jewelry for Bebe. Her designs were criticized for being runway knock-offs, but the star defended her line, stating, The clothes you see in the chain stores at your mall are all inspired by designer, runway fashion!!! What stores like Bebe do is take runway fashion and use it as inspiration to create pieces that are wearable and accessible for everyone.  

To say any of our pieces are knockoffs is to say every item in your mall is a knockoff.

Melissa Molinaro

This curvy brunette Molinaro, 28, unlike Kardashian, has proven to have a somewhat successful music career. She was a competitor on the show 'Pussycat Dolls Present: The Search For the Next Doll' and 'Making The Band 3.' She is a model, currently starring in the Old Navy campaign, Super C-U-T-E and is in the new film Honey 2. She is a skilled dancer and this month released her debut single Dance Floor, which has a catchy techno beat, in line with current trends.

Molinaro told E! that she got the Navy campaign based on her dance and music background, though people have speculated that she got the job because she looked like Kardashian. To me is extremely flattering, I mean she is a beautiful woman in her own right....and I'm flattered. That's an amazing compliment, the singer says of being compared to Kardashian.
