Invicta just dropped a bombshell on the MMA world. Well, a "Time Bomb," that is.

Tiffany Van Soest, one of the top female Muay Thai fighters and kickboxers in the world, has signed a deal with Invicta FC, sources told MMA Fighting on Thursday. Van Soest has long spoken about crossing over to MMA and now she'll do so with Invicta, with her debut likely coming this summer.

The news comes on the heels of Van Soest signing with GLORY kickboxing, which MMA Fighting reported Wednesday.

Van Soest, 27, is a huge pickup for both promotions, which coincidentally have broadcast deals with UFC Fight Pass. "Time Bomb" will make her GLORY debut at GLORY 30 SuperFight Series on May 13 against Jeri Sitzes in a rematch of their 2012 Muay Thai fight, sources said. The fight will air live on Fight Pass.

Van Soest is the former Lion Fight super bantamweight and featherweight champion. The karate black belt also held the WBC Muay Thai international super bantamweight title. Van Soest hails from Southern California, but now lives and trains in Bali.

In Invicta, Van Soest will compete in the already loaded strawweight division. She is a longtime training partner of well-known MMA fighters like Joe Schilling, Carla Esparza and Jessica Penne. "Time Bomb" is known for her aggressive, exciting fighting style.
