After her split from fiancé Matt Bellamy last year, actress Kate Hudson was rumored to have had a fling with "Dancing With the Stars" pro dancer Derek Hough. Now, it looks like Kate and Derek have rekindled their romance after spending a lot of time together in recent weeks. 

According to Us Weekly, the "Almost Famous" actress and the "DWTS" pro attended a U2 concert at The Forum in Inglewood, California on May 26. The two were joined by Hough's sister, Julianne Hough, and her boyfriend Brooks Laich. 

The pair reportedly met outside the venue and held each other close, pressing their cheeks together as they said hello. 

"She hugged him and they kept their arms around each other for a while before actually letting go," said an insider to Us Weekly. 

Hudson wore a denim jumpsuit under a tie-dyed cardigan and accessorized with black platform sandals, while Hough was also casually attired in jeans, a white shirt, brown boots, and a grey newsboy cap. 

On May 29, the pair was spotted once again at The Forum for another U2 concert. That same day, Hough was photographed dropping the 36-year old off at her car in West Hollywood. 

Earlier in May, Hudson showed up to watch Hough perform on the hit ABC show. The two are said to have become close after the 30-year old gave the "Deepwater Horizon" actress dancing lessons last year, and it was claimed that they became more than friends. 

A source revealed to Us Weekly that Hough and Hudson were kissing as they hung out at West Hollywood hot spot The Nice Guy in December, days before the actress confirmed her split from Bellamy. 

Hudson has a four year old son, Bingham, with the Muse frontman. She is also a mother to 11-year old son Ryder from her marriage to Chris Robinson. She separated from the Black Crowes frontman in 2006 after five and a half years of marriage.
