It's been less than a week since Leah Messer returned home from rehab, but the Teen Mom 2 star is diving right back into her fast-paced romance with boyfriend T.R. Dues.
RadarOnline.com can exclusively reveal that the two-time divorcee, 23, and her personal trainer lover, 32, threw a party at a local pool this week with his two young sons, Tyshawn, 8, and Angelo, 4.
And sources say the couple of two months is already looking for a home to call their own.
"They are talking about getting their own place together," a family insider says of the MTV star, who is currently living with her mother Dawn.
And size definitely matters. Messer currently has joint custody of her three daughters, 5-year-old twins Ali and Aleeah and 2-year-old Adalynn, while Dues' sons spend about half of their time with dad.
"It's going to need to be a big house, with five kids running around!" says the source.
As Radar exclusively reported, Messer and Dues began dating when he helped her work on her fitness in late April.
But there was a bit of overlap. She didn't finalize her divorce from husband Jeremy Calvert, 27, until June 8.
Last Sunday, Messer completed a month in rehab to deal with her infamous pill problem and emotional issues, and is currently doing well, the source insists: "She seems happy."
The new season of Teen Mom 2 premieres on July 9.
