Owl Slider - Adding Hover Effect on Custom Nav Tabs on Auto Slide

Owl Slider - Adding Hover Effect on Custom Nav Tabs on Auto Slide

I am using Owl Carousel http://owlgraphic.com/owlcarousel/

I have created custom Navigation Tabs, clicking Tab1 takes me to Slide 1, Tab 2 - Slide 2...and so on .
I keep Autoplay On but how do i apply hover effect on the Tab1 when Slide 1 is "active" or Tab2 when Slide 2 is "active". 
For Example on autoSlide, 
      If Slide 1 is active - the Tab 1 gets highlighted and
      If Slide 2 is active - Nav Tab 2 gets highlighted. 

Can some one help me..
