Vicki Belo and Hayden Kho break up because of Nancy Castiglione?

It’s chismisan time once again. Is it over between celebrity doctor Vicki Belo and Hayden Kho, Jr. who got engaged in December 2010?

It all started with a tweet by Belo:

@vicki_belo - nancycastilogne (sic) you can now openly date @haydenjr . You have my blessings . Hope you'll both be happy

Hayden then tweeted

@haydenjr - Before things go out of hand: Vicki and I are just having a misunderstanding. Don't make conclusions. There's NO infidelity issue here.

According to abs-cbnnews.com, Kho was allegedly spotted earlier this week kissing Castiglione at a bar in Taguig.

Meanwhile, Nancy Castiglione, Filipino-Italian actress/model/host and now a mother of twins has not tweeted anything since yesterday. Her twitter account is @nancyjc24.
