Kate Hudson Boyfriend Derek Hough ‘DWTS’ Sister Slams Dating Rumors?

Despite the fact the it was their publicly making out that tipped off the media that Kate Hudson had split with longtime fiancé, Matthew Bellamy, Goldie Hawn's buxom blonde daughter has avoided talking about her relationship with Dancing with the Stars boyfriend, Derek Hough, at all cost. According to the latest gossip news updates, the Instagram bikini model has been seen spending time with the Mormon hunk all over L.A. in recent weeks -- leading folks once again to assume that the pair must be dating. Hough's sister, Julianne, is now sticking up for her 30-year-old, however, with the TV show judge insisting that her brother has avsolutely no love life at all, or else she would know about it.

After they made the mistake of letting it look like their budding relationship had broken up her near-marriage to Muse frontman, Mathew Bellamy, Kate Hudson and Derek Hough seemed to take a little time off from hanging out with one another in public.

The folks at Us Weekly are now reporting that the self-imposed ban on PDA has seemingly been lifted and Derek and Kate are now allowing themselves to be seen in each other's company once again:

"The Deepwater Horizon actress, 36, and Hough, 30, recently rocked out together at U2's concert at The Forum in Inglewood, Calif., on May 26.

"Three nights later, the twosome headed back to The Forum for another U2 show on May 29... Afterward, the two partied with Breaking Bad alum Aaron Paul at The Roxy."

While anyone with eyes can plainly see that a love connection is definitely developing between the blonde beauties, Derek's sister and Dancing with the Stars costar, Julianne Hough, told E! News point blank that there was absolutely no way that her brother was seeing anyone without her knowing about, and she doesn't know anything:

"Derek doesn't have a love life. I live with him, so there's no way he could have one."

Proving that he's not as eloquent as he is light footed, Derek seconded his sister nonsense -- claiming that he was practically married to his work for the time being and had no time for frivolous pursuits of the heart:

"You know me...This tour is my love life.

"I don't really have a love life."

Yeah, well Kate Hudson definitely does and you can't just explain hanging out with her night-after-night by talking about how much you just love dancing...and P.S. no one is fooled by your little "I live with my sister" routine either.
