Tamar Braxton confirmed Tuesday that she and her husband are expecting their first child together.

Will she follow in the footsteps of her uber-famous family and start a big one of her own? Probably not, she says.

“I’m only having one!” Braxton quipped Thursday in an exclusive video interview with Celebuzz, adding: “This is a once in a lifetime experience.”

Also in our exclusive chat: Braxton — who stars alongside sisters Toni, Traci, Towanda, Trina and mom Evelyn in tonight’s season 3 premiere of Braxton Family Values  (9/8c on WE) — gives us the scoop on what she may or may not name her baby, her pregnancy cravings and whether she’ll ever stop being pregnant in heels.

Watch now in the video, above.

Viewers got to know Tamar Braxton first on WE’s Braxton Family Values, but we really got to know her a lot better on her spinoff with her husband, music manager Vince Herbert, Tamar & Vince.

“When Tamar & Vince first started, it was a lot to watch only because Vince and I was kind of going through something in our marriage,” Braxton tells Celebuzz in our Hollywood studio this week.

“And we had to get through that rough spot to get to where we are now,” she continues. “I’m so excited to see us grow as a couple and individually and you get to see me grow as an artist.”

Fans also watched as Braxton worked on her solo career for all of us to watch. And it all culminates with a showcase on Thursday’s finale.

“I’m just so excited, because you get to hear Love And War,” Braxton said of the year-ender. “And I’ve been working really hard on this album to make sure it was up to my standards. Because in the past, I just felt like I’ve done music that was up to other people’s standards. Everybody wanted me to sing songs like [my sister] Toni [Braxton]. That’s not the kind of artist that I am.”

“I really wanted to make sure that you get to see my sassiness, my fun-ness and, you know, me popping and dropping. I’m definitely doing that,” the 35-year-old adds.

Watch our full interview with Tamar above.

The Tamar & Vince season finale airs Thursday at 9 PM on WE.

Out with the old and in with the new — new digs, that is!

The younger sis of Grammy award-winner Toni Braxton, Tamar Braxton, 35, and her hubby Vincent Herbert – the music executive who discovered Lady Gaga — have decided to sell their French Country-style mansion in the star-studded city of Hidden Hills, Calif.

The Tamar & Vince reality stars just purchased their 12,402 square foot pad in September 2011, but have already opted for a change and have launched the mansion back on the market for a whopping $7,595,000.

How much did they raise the price?

According to The Real Estalker, the Braxton-Herbert clan originally purchased their property for less than their asking price of either $6,900,000 or $3,400,000 based on multiple listing sources.

The mansion encompasses 1.31 acres of land, including a McMansion-style double height entry-way, curved staircases, a spacious living room, and a cozy library featuring specialized panels and a house-warming fireplace.

Plus, their lovely abode has a fancy dining room with open-beamed ceilings, and a wine cellar, in addition to a bar in the game room — all of which revoleves around an island kitchen that centers the family room with a fireplace and surround-sound home theater.

Aside from the gorgeous hilly views from the backyard, the landscaping is fab — including several porches and patios, a barbecue pit, fountain, swimming pool, and spa for the perfect outdoor party.

That’s not even everything. The formal listing includes a plethora of other special amenities that make the five bedroom mansion extra special.
