`We are just good friends', this has been the slogan of several stars when they don't want to disclose their relationship with each other in public. The latest addition to this list is American actress Demi Lavato, who also chose to pick up the line for her alleged link up with the host `Yo Mamma' in MTV.

Lovato broke up with her former beau Joe Jonas in last May and since then she has found support in the arms of Wilmer and many has claimed that they are a couple. However, Demi has not accepted the fact and said that she is just getting emotional support from her close buddy.

Demi and Wilmer met in March when they shot a public-service announcement for supporting earthquake relief in Chile. Recently, Demi underwent a treatment about which her representative said that it was just for `emotional and physical issues'.

However, sources reveal that the 18-year-old got Wilmer was introduced to her friends as her boyfriend. So, why is she in denying the fact that she is dating Wilmer? Is it the fluctuating past of Wilmer that is keeping her worried? Wilmer had dated Mandy Moore, Lindsay Lohan and reported have slept with Jennifer Love Hewitt and Ashlee Simpson as well. This could be the reason behind her denial.

Well, she has been heartbroken just few days back so probably she does not want to take the risk so soon again!
