CIARA SET TO SPEND THANKSGIVING WITH 50 CENT!!

Let's see 50 Cent and Ciara deny their relationship after this. has learned that Ciara is traveling across Eastern Europe with 50 Cent as he tours. And word is, she's not traveling as a performer - but as 50's companion.

And there's more. has learned that Ciara and 50 are so serious, that she's spending Thanksgiving with him - and not with her family in Atlanta.

Don't believe us, well check out the photo showing Ciara in Brastislava outside 50 Cent's hotel (with 50's tour manager). Why else would she be in Slovakia - it ain't exactly a tourist spot...
