When the former BFFs — Heidi Montag and Lauren Conrad — parted ways, the new season of “The Hills” gave way to a new duo who took over the show.

No, I’m not talking about “Speidi” (as a brilliant EW Hills blogger calls Spencer and Heidi). Nor am I referring to Lauren and Audrina.

Nope, I’m talking about Brody and Frankie.

In case you’re not a fan of the show, Brody and Frankie are the two guys who met through their mutual acquaintance Lauren and became best bros, albeit, by default.

You see when Spencer and Heidi started dating, they both shunned their respective BFFs, Brody and Lauren.

After much bickering, Lauren sided with her new BFF Audrina, and Brody started to hang with his new pal Frankie Delgado.

I wouldn’t make such a big deal between Brody and Frankie hanging out but the two have been paling around a lot more on “The Hills” and in L.A.

They’re blossoming friendship became even clearer to me when I was watching “Keeping up with the Kardashians.” Brody and Frankie were babysitting together during a recent episode of that horrible reality TV show on E!

Why were they there you ask?

You see, “The Kardashians” features the family of Kim Kardashian, the Paris Hilton pal who also made a sex tape with her ex Ray-J and later posed for Playboy. Anyhow, Kim’s step-father is none other than the Olympic gold medalist Bruce Jenner, who also happens to be Brody’s dad.

Apparently Brody leaves “The Hills” once in a great while, and visits his reality TV family on the “Kardashians.” Though he left Lauren behind, in the episode I watched, Brody brought along Frankie and they ended up babysitting the youngest Kardashians.

Though I despise the horrible “The Kardashians,” show, watching it gave birth to an intriguing idea — why not give Brody and Frankie their own show?

Brody and Frankie, or as I now like to say, “Brokie,” could be a guys version of “The Hills,” sort of like a real-life “Entourage.” And with most of “The Hills” viewership being female or gay, I think giving Brokie more screen time could be a ratings winner.

Until that happens, watch “The HIlls” at 11 p.m. Mondays on MTV.

Here’s a pic of Brody and Frankie wearing Batman and Robin Halloween costumes….for reals.
