Vanessa Lachey is taking her pregnancy to new heights!

The first-time mom-to-be is expecting a baby boy in the fall with hubby Nick Lachey and hasn't had to quit traveling just yet. The Wipeout hostess, 31, was shocked to discover she could still fly despite how far along she is in her pregnancy.

"I can't believe you are allowed to fly pregnant all the way up to 36 weeks!" she tweeted Wednesday. "Then no more! That's pretty far along."

She quickly added to her concerned followers, "P.S., I don't intend to be flying close to 36 weeks! After my Dr.'s OK and compression thigh highs in tow, I'm ready for one last work trip."
