Donnie Wahlberg, Jenny McCarthy Dating: New Kids on the Block Member's New Girlfriend? 'Jenny McCarthy Show' Interview [VIDEO]

We have a new couple in Hollywood. Jim Carrey's former girl Jenny McCarthy and Mark Wahlberg's slightly less famous brother Donnie Wahlberg were spotted together on Fourth of July. An Us Weekly source confirms that the blonde bombshell and the former New Kids on the Block singer are currently an item. They not only spent the July 4th holiday together, but they also reportedly spent time with Wahlberg's New Kids on the Block buddy Jordan Knight and his boyfriend Harley.

"Yes, they recently started dating and are having a lot of fun," a source told Us Weekly. "They had a blast 4th of July hanging out with a bunch of their friends." Us Weekly also reported that Wahlberg's reps had no comment. However, usually with a new celebrity couple, they let the news break on its own. I wouldn't be surprised if we see the two together on a red carpet premiere very soon.

McCarthy has a son from a previous relationship and recently dated actor Jim Carrey for about five years before breaking up in 2010. As Us Weekly notes, Wahlberg was a guest on The Jenny McCarthy Show earlier this year and they seemed to be enjoying each other's company. Donnie Wahlberg was previously married to Kim Fey, before they divorced back in 2008. Wahlberg has two children.

Do you think this new couple will last? Both are older and wiser than with their previous relationships, so who knows, it could have legs. Comment below with your thoughts on this new rumored couple.
