vanessam460.jpgWatch out Brooke Burke! Looks like Vanessa Minnillo is pulling out her stilettos and some big hair to try to land the coveted hosting spot next to Tom Bergeron on Dancing With The Stars.

Nick Lachey's lady has had plenty of hosting experience with MTV's TRL, Entertainment Tonight and most recently as host of ABC's reality series True Beauty.

X17online captured these exclusive pics of Miss V working it in this short, form-fitting blue number at the CBS Studios in Studio City yesterday. When in doubt, pull out the Christian Louboutins!

Not just Brooke and Vanessa are in the running - reports claim that DWTS alum and former winner Melissa Rycroft will also be screen testing.

Hold on to your extensions...this may be an all-out cat fight!

We've been told that next week, ABC will officially announce the host. With all this fierce competition surrounding the hosts...what about the actual cast? The big announcement of the all-star lineup won't happen until March 1st.

ABC's Dancing With The Stars Season 10 premieres on March 22.
