Nancy Grace couldn't make a case to stay another week on Dancing With the Stars.

The 52-year-old HLN host and pro partner Tristan MacManus were voted off the ABC hit Tuesday, just six days before the semi-finals. Rob Kardashian, 24, joined Grace in the bottom two with his partner, Cheryl Burke, 27.

"I am so proud, but I really cannot take the credit. It's been all Tristan from the get-go," Grace said after getting the axe. "To the whole crew at Dancing With the Stars, my family who flew out here to take care of my twins so I could dance, and especially Tristan, I thank you."

MacManus, 29, said he "had a blast" working with the Georgia native. "We can't be disappointed to make it this far," he told co-hosts Tom Bergeron and Brooke Burke. "From the start, we've always said to each other, 'It's not about being the best -- it's just about doing your best.' I think that's what we did."

Grace and MacManus earned the lowest cumulative score Monday night (44/60). The remaining Dancing With the Stars contestants include Kardashian, soccer player Hope Solo, 30, actress and TV host Ricki Lake, 43, and actor and army veteran J.R. Martinez, 28.
